That's just plain wrong -- the lens on the FZ8, most notably, is
objectively equal to or better than the great majority of dSLR lenses,
despite much lower cost. That clearly seems to bug the hell out of dSLR
fans, who apparently feel so threatened they have to try to put it down.
Not even live and let live, much less give the devil his due.


Truly, even if true that does not bug any "dslr fans" in the slightest
because it has absolutely no bearing whatsoever on the end result.
You're picking just one aspect of lens performance, ie resolution.

You are ignoring the objective evidence that even if that lens had
twice the resolution, it wouldn't come through in the final images
because of the limitations of the small sensor.

Seriously, why do you think the lens on the camera you happen to like
poses any "threat" whatsoever to the users of other types of cameras?
You must imagine that they all have the same ego that you do.

The proof of the pudding is in the eating, as they say; and any
objective real-world comparison of images from the FZ8 with most dslrs
shows the former to be lacking.

To quote the conclusions in dpreview:

-Some areas of performance actually worse than predecessor
-Noise is, as usual, a bit of a problem at lower ISO settings
ISO 400+ noise reduction produces color bleeding and loss of low
contrast detail
-Default noise reduction too high at all ISO settings (use low NR
setting)
-Limited dynamic range, highlight clipping in JPEGs
-Default contrast a bit on the high side
-Occasional (mild) fringing
-Occasional focus hunting at long end of zoom in low light and in
macro mode
-Slight video lag in live preview makes very short shutter lag rather
pointless

So it really doesn't matter if the resolution of the lens is somewhat
better than some dslr lenses. In many images, the higher noise and
limited dynamic range detract from the image far more than a few lines
of resolution.


Why ignore those facts and continue to take this defensive position?
It sounds like you are the one who feels threatened.


Chill out and try to enjoy life for what it is, rather than for
what it is not.


I respectfully suggest you take your own advice, and try to have a bit
more objectivity. Surely these holidays are a good excuse for the
positive.



That's all we've been asking you to do. Accept the objective
evidence and stop turning into some kind of personal vendetta towards
you because you happen to like using those cameras.




Dear Resident-Troll,

Many (new & improved) points outlined below completely disprove your usual
resident-troll bull****. You can either read it and educate yourself, or don't
read it and continue to prove to everyone that you are nothing but a
virtual-photographer newsgroup-troll and a fool.


1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

As you do sometimes have good points to make, and as I would have liked to

Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models

even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

David, I'd rather not get involved in parts of this debate but what

of one or two specific images that John is somehow translating into
the perception that his choice of camera type is being attacked. Of
course, it is not as best I can see. Quality is quality is quality,
and not is not is not. Since I have no skin in the game, I'm not
going to further engage.


With all due respect, Jerry, there's a world of difference between a
fair and balanced critique, and focusing on just negative issues, real
and imagined. Worse, this wasn't about images I posted, it was about
bashing of an image dredged up from my website by someone looking for a
bad image to put down, and after I had explained the image was not
representative of the camera. This was then compounded by posting a
good image claimed to be comparable (on only superficial grounds).
If it's not an "attack", then it's at least an unfair putdown that
strongly suggests bias.


Regardless of your mistaken impression of the motives of others, it is
only a comparison of cameras... NOT you or your ability. Why do you
keep making it to be so?

Many of your pictures do in fact demonstrate a keen eye for
photography. It's just that you could be doing a much better job at
it with a better camera.

You've been told before that the images in question were taken AT
RANDOM from your website. They were NOT chosen to be the worst
possible example in order to put you down. There were many worse
images there to choose from if the goal was just to be nit picking.
(Again, that refers to the CAMERA, not to you.)

And the same comments have applied toward some of the images that you
specifically chose as examples.


When I shoot an event, I often do a lot of snaps for competitors, and
because of limited time between the event and post-event socializing,
put them through a crude automated correction and compression that
results in a pleasing screen/slide-show image, but that degrades the
image at the pixel level. Thus these images are not representative of
the camera, and using them to put it down is unfair bashing.



But don't you see, this just further illustrates the point. Images
from a better camera simply don't need the same level of post
processing correction to make them look acceptable.


Self-evident. You've just proved that DSLR's are not the better camera.

Instead of using the lower quality of DSLR gear where you must resort to tedious
editing of the RAW data to get any image worth using out of it, you can very
often use the properly produced JPG file right from the P&S camera.

By your own comment you have just proved that P&S cameras are better than any
DSLR, otherwise you wouldn't need your camera to produce RAW files.

Get your dslr-troll-schtick worked out. You ****ed-up royally on this one.

Ah, well that's where I first got into trouble. I looked at an

visible on close viewing, even though I said that these defects
may not be visible on a small print!


The defects aren't visible in a large print either -- you'd presumably
know that if you had actually printed it, as I did, instead of just
speculating -- but that wasn't the issue, as you know. That particular
image was dredged up by someone hunting through my website for something
bad to put down, not something posted here by me, and you jumped in with
your own put down. You had nothing to say about the images I posted,
nothing positive or constructive to say about the dredged up image, and
nothing at all to say about the dredged up image itself, just technical
bashing of that image. You then selected a good dSLR photo of your own
to compare to it. Neither accurate nor fair nor balanced nor helpful.


Actually, at least two people posted different photos selected at
random, not something that was dredged up.

Both of them were typical of that class of camera, as verified by
virtually any nonbiased review of those cameras. They weren't poor
photographs, they simply showed the kind of noise and artifacts that
those cameras are known for.

As to being helpful, yes it was. If nothing else, a newbie reading
all of this will have seen evidence of what different kinds of cameras
can produce rather than listening to enthusiasts on either side
bragging about their gear.

John, it really isn't a witch hunt. Most of us who have used those
kinds of cameras and who have graduated to ones with larger sensors
have simply come to grips with the issues, and made the appropriate
changes. Nobody is trying to trash you personally.


You didn't "graduate" by moving to a larger sensor, you were foolishly shoved
back into last-century's classes without realizing it. Others only made you
think that you were "graduating"; and you bought it, lock stock and barrel.
That's how amazingly stupid you are. You went 10 grade-levels back by putting up
with excess audible noise, slow flash-sync, dirt on sensors, overpriced
less-sharp optics, and hundreds of other drawbacks to "graduating" to a DSLR.

Here, let's list just a few of those DSLR drawbacks vs. true P&S graduation
classes for you:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

The point is that some can be used in a derogatory way without trying,

Sorry, but only in the most exceptional circumstances would I consider not
calling a P&S a P&S. Even a DSLR can be a P&S camera - mine even has a
special position on the command-dial for it, marked in green, so it's easy
to find! In normal use of my DSLR and non-DLSR cameras, I regularly make
use of automatic exposure and automatic focussing. Does that make them
P&S? G

And I'll add to that: Whenever I go to get my camera, I never, ever
think, "I'm going to go pick up my dslr." It's a camera, period. I
could care less if someone calls it a moon rock... it's what I do
with it that matters. Period.

But the fact remains that the larger sensor in a dslr camera will
outperform the smaller sensor in a p&s every time under the same
conditions. If small size and convenience are more important to you
than image quality, by all means use the smaller one. However, if
image quality and flexibility are more important to you, then choose
the larger one.



Dear Resident-Troll,

Many (new & improved) points outlined below completely disprove your usual
resident-troll bull****. You can either read it and educate yourself, or don't
read it and continue to prove to everyone that you are nothing but a
virtual-photographer newsgroup-troll and a fool.


1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths

P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

Will you live up to your promise this time?

Are you kidding?!? That ego cannot be contained.




Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as

needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

Irrelevant. The amount of information has nothing to do with pixels.

it has everything to do with pixels. the exact same data can be
displayed without the need to scroll on either screen. the only
difference is one is a little smaller than the other.


Not so, that's just a matter of scaling.

and as for the price, yes, apple does not have a $500 laptop at this
time. they do have $1000 laptop and it is competitive with $1000
laptops from other companies.

Sorry, but no, twice as expensive as a fully-featured PC notebook
computer, as I've shown..

as i've shown, the $1000 macbook has more features than the $500 dell,
so it's no surprise it costs more.


Also irrelevant.

anyway, since we agreed on the discussion being over, it's over.


Good.

STFU, NavASS, you "Peerless Idiot".




Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

No offense (sincerely), but that seems a bit over the top to me.

What rights and freedoms are you giving up? Saying the "n" word?

I'm ****ing sick and tired of being called

What "vile names"? Seriously.

It's like your fetish about being offended by the term "P & S".


With all due respect, Jerry, you can't have it both ways, to complain

To
the millions of other people, this merely means a smallish, less

CHOOSE to be offended and sure enough, you are!


Just as you "CHOOSE" to use the term, even though you know it to be
inaccurate, and to be offensive to me, not the term itself, but the
inappropriate way it is being used. There is a difference, as I'm sure
you know.

Cameras like the FZ8 are actually most commonly called "super-zoom" by
knowledgeable people, their defining characteristic, not "point and
shoot". And Panasonic, like other manufacturers, uses the term "compact
digital" to refer to its Lumix cameras in general, not "point and
shoot".

You do of course have a right to call cameras like the FZ8 whatever you
want, but that doesn't mean you get a pass on your _choice_ of term.
Fair enough?


All this over the way that most people prefer to call a certain class
of camera, including camera manufacturers and retailers? And none
of which has absolutely anything to do with using any camera to create
real photographs?

Well, Merry Christmas to everyone.

And if the word "Christmas" offends anyone, too bad. Jesus is the
reason for the season. Deal with it! :-)


Their virgin mary was just a name they carved over the name of Isis on her
statues. The virgin birth was stolen from a more ancient Pagan Roman legend. The
"resurrection" was a *******ization of the holiday of Eostre, the Pagan Goddess
of spring, to celebrate the resurrection of life in a northern climate, a
holiday over 3500 years old. No mother, no birth, no resurrection = no christ.

But besides that:




Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

It doesn't bug people, it amuses them. Jesus has nothing to do with the

the commercialization of Christmas when in reality that's the only part
that makes any sense.


I don't think anyone believes Jesus was born on December 25th. But for
various historical reasons that what has been chosen to celebrate the
event since nobody knows the exact date. There is a reason it is
called CHRIST-mas, after all. Otherwise it would just be a very
expensive way to note the passing of the winter solstice.


The origin of the christmas tree is when christians cut down the live decorated
trees that your Pagan ancestors had outside. They couldn't burn them so they hid
them in their homes, then invented the "christmas" holiday to try to explain
this destruction of their neighbors' property to their children and cover up
their vandalism. christians = destructive lying thieves, still being proven to
this very day when they reenact this event in their homes every Winter Solstice.
As recorded by Charlemagne, "And they cut down the mighty pagan tree, and up
sprang the birth of our christ."

Their virgin mary was just a name they carved over the name of Isis on her
statues. The virgin birth was stolen from a more ancient Pagan Roman legend. The
"resurrection" was a *******ization of the holiday of Eostre, the Pagan Goddess
of spring, to celebrate the resurrection of life in a northern climate, a
holiday over 3500 years old. No mother, no birth, no resurrection = no christ.

But besides that:




Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the

comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the

accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your

laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter

of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that

than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths
allow for the deep DOF required for excellent macro-photography when using
normal macro or tele-macro lens arrangements. All done WITHOUT the need of any
image destroying, subject irritating, natural-look destroying flash. No DSLR on
the planet can compare in the quality of available-light macro photography that
can be accomplished with nearly any smaller-sensor P&S camera. (To clarify for
DSLR owners/promoters who don't even know basic photography principles: In order
to obtain the same DOF on a DSLR you'll need to stop down that lens greatly.
When you do then you have to use shutter speeds so slow that hand-held
macro-photography, even in full daylight, is all but impossible. Not even your
highest ISO is going to save you at times. The only solution for the DSLR user
is to resort to artificial flash which then ruins the subject and the image;
turning it into some staged, fake-looking, studio setup.)

13. P&S cameras include video, and some even provide for CD-quality stereo audio
recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine
the gaping hole in our history of the Hindenberg if there were no film cameras
there at the time. The mystery of how it exploded would have never been solved.
Or the amateur 8mm film of the shooting of President Kennedy. Your video-ready
P&S camera being with you all the time might capture something that will be a
valuable part of human history one day.

14. P&S cameras have 100% viewfinder coverage that exactly matches your final
image. No important bits lost, and no chance of ruining your composition by
trying to "guess" what will show up in the final image. With the ability to
overlay live RGB-histograms, and under/over-exposure area alerts (and dozens of
other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some
external LCD histogram display, ruining your chances of getting that perfect
shot when it happens.

15. P&S cameras can and do focus in lower-light (which is common in natural
settings) than any DSLRs in existence, due to electronic viewfinders and sensors
that can be increased in gain for framing and focusing purposes as light-levels
drop. Some P&S cameras can even take images (AND videos) in total darkness by
using IR illumination alone. (See: Sony) No other multi-purpose cameras are
capable of taking still-frame and videos of nocturnal wildlife as easily nor as
well. Shooting videos and still-frames of nocturnal animals in the total-dark,
without disturbing their natural behavior by the use of flash, from 90 ft. away
with a 549mm f/2.4 lens is not only possible, it's been done, many times, by
myself. (An interesting and true story: one wildlife photographer was nearly
stomped to death by an irate moose that attacked where it saw his camera's flash
come from.)

16. Without the need to use flash in all situations, and a P&S's nearly 100%
silent operation, you are not disturbing your wildlife, neither scaring it away
nor changing their natural behavior with your existence. Nor, as previously
mentioned, drawing its defensive behavior in your direction. You are recording
nature as it is, and should be, not some artificial human-changed distortion of
reality and nature.

17. Nature photography requires that the image be captured with the greatest
degree of accuracy possible. NO focal-plane shutter in existence, with its
inherent focal-plane-shutter distortions imparted on any moving subject will
EVER capture any moving subject in nature 100% accurately. A leaf-shutter or
electronic shutter, as is found in ALL P&S cameras, will capture your moving
subject in nature with 100% accuracy. Your P&S photography will no longer lead a
biologist nor other scientist down another DSLR-distorted path of non-reality.

18. Some P&S cameras have shutter-lag times that are even shorter than all the
popular DSLRs, due to the fact that they don't have to move those agonizingly
slow and loud mirrors and shutter curtains in time before the shot is recorded.
In the hands of an experienced photographer that will always rely on prefocusing
their camera, there is no hit & miss auto-focusing that happens on all
auto-focus systems, DSLRs included. This allows you to take advantage of the
faster shutter response times of P&S cameras. Any pro worth his salt knows that
if you really want to get every shot, you don't depend on automatic anything in
any camera.

19. An electronic viewfinder, as exists in all P&S cameras, can accurately relay
the camera's shutter-speed in real-time. Giving you a 100% accurate preview of
what your final subject is going to look like when shot at 3 seconds or
1/20,000th of a second. Your soft waterfall effects, or the crisp sharp outlines
of your stopped-motion hummingbird wings will be 100% accurately depicted in
your viewfinder before you even record the shot. What you see in a P&S camera is
truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."

The season actually came from pagan rituals, as can be seen in the
history of Santa Claus, decorated trees, etc. Christians just jumped on
the bandwagon.

Much like you jumping in everywhere with irrelevant and misleading bull****?

Nope, think not...




The origin of the christmas tree is when christians cut down the live decorated
trees that your Pagan ancestors had outside. They couldn't burn them so they hid
them in their homes, then invented the "christmas" holiday to try to explain
this destruction of their neighbors' property to their children and cover up
their vandalism. christians = destructive lying thieves, still being proven to
this very day when they reenact this event in their homes every Winter Solstice.
As recorded by Charlemagne, "And they cut down the mighty pagan tree, and up
sprang the birth of our christ."

Their virgin mary was just a name they carved over the name of Isis on her
statues. The virgin birth was stolen from a more ancient Pagan Roman legend. The
"resurrection" was a *******ization of the holiday of Eostre, the Pagan Goddess
of spring, to celebrate the resurrection of life in a northern climate, a
holiday over 3500 years old. No mother, no birth, no resurrection = no christ.

But besides that:




Dear Resident-Troll,

Your reply is completely off-topic. Here are some (new & improved) topics that
befit this newsgroup. Please consider them for future discussions and posts:



1. P&S cameras can have more seamless zoom range than any DSLR glass in
existence. (E.g. 9mm f2.7 - 1248mm f/3.5.) There are now some excellent
wide-angle and telephoto (telextender) add-on lenses for many makes and models
of P&S cameras. Add either or both of these small additions to your photography
gear and, with some of the new super-zoom P&S cameras, you can far surpass any
range of focal-lengths and apertures that are available or will ever be made for
larger format cameras.

2. P&S cameras can have much wider apertures at longer focal lengths than any
DSLR glass in existence. (E.g. 549mm f/2.4 and 1248mm f/3.5) when used with
high-quality telextenders, which do not reduce the lens' original aperture one
bit. Following is a link to a hand-held taken image of a 432mm f/3.5 P&S lens
increased to an effective 2197mm f/3.5 lens by using two high-quality
teleconverters. To achieve that apparent focal-length the photographer also
added a small step of 1.7x digital zoom to take advantage of the RAW sensor's
slightly greater detail retention when upsampled directly in the camera for JPG
output. As opposed to trying to upsample a JPG image on the computer where those
finer RAW sensor details are already lost once it's left the camera's
processing. (Digital-zoom is not totally empty zoom, contrary to all the
net-parroting idiots online.) A HAND-HELD 2197mm f/3.5 image from a P&S camera
(downsized only, no crop):
http://farm4.static.flickr.com/3141/...1dbdb8ac_o.jpg Note that any
in-focus details are cleanly defined to the corners and there is no CA
whatsoever. If you study the EXIF data the author reduced contrast and
sharpening by 2-steps, which accounts for the slight softness overall. Any
decent photographer will handle those operations properly in editing with more
powerful tools and not allow a camera to do them for him. A full f/3.5 aperture
achieved at an effective focal-length of 2197mm (35mm equivalent). Only DSLRs
suffer from loss of aperture due to the manner in which their teleconverters
work. P&S cameras can also have higher quality full-frame 180-degree circular
fisheye and intermediate super-wide-angle views than any DSLR and its glass for
far less cost. Some excellent fish-eye adapters can be added to your P&S camera
which do not impart any chromatic aberration nor edge softness. When used with a
super-zoom P&S camera this allows you to seamlessly go from as wide as a 9mm (or
even wider) 35mm equivalent focal-length up to the wide-angle setting of the
camera's own lens.

3. P&S smaller sensor cameras can and do have wider dynamic range than larger
sensor cameras E.g. a 1/2.5" sized sensor can have a 10.3EV Dynamic Range vs. an
APS-C's typical 7.0-8.0EV Dynamic Range. One quick example:
http://farm4.static.flickr.com/3142/...7ceaf3a1_o.jpg

4. P&S cameras are cost efficient. Due to the smaller (but excellent) sensors
used in many of them today, the lenses for these cameras are much smaller.
Smaller lenses are easier to manufacture to exacting curvatures and are more
easily corrected for aberrations than larger glass used for DSLRs. This also
allows them to perform better at all apertures rather than DSLR glass which
usually performs well at only one aperture setting per lens. Side by side tests
prove that P&S glass can out-resolve even the best DSLR glass ever made. See
this side-by-side comparison for example
http://www.cameralabs.com/reviews/Ca..._results.shtml
When adjusted for sensor size, the DSLR lens is creating 4.3x's the CA that the
P&S lens is creating, and the P&S lens is resolving almost 10x's the amount of
detail that the DSLR lens is resolving. A difficult to figure 20x P&S zoom lens
easily surpassing a much more easy to make 3x DSLR zoom lens. After all is said
and done you will spend anywhere from 1/10th to 1/50th the price on a P&S camera
that you would have to spend in order to get comparable performance in a DSLR
camera. To obtain the same focal-length ranges as that $340 SX10 camera with
DSLR glass that *might* approach or equal the P&S resolution, it would cost over
$6,500 to accomplish that (at the time of this writing). This isn't counting the
extra costs of a heavy-duty tripod required to make it functional at those
longer focal-lengths and a backpack to carry it all. Bringing that DSLR
investment to over 20 times the cost of a comparable P&S camera. When you buy a
DSLR you are investing in a body that will require expensive lenses, hand-grips,
external flash units, heavy tripods, more expensive larger filters, etc. etc.
The outrageous costs of owning a DSLR add up fast after that initial DSLR body
purchase. Camera companies count on this, all the way to their banks.

5. P&S cameras are lightweight and convenient. With just one P&S camera plus one
small wide-angle adapter and one small telephoto adapter weighing just a couple
pounds, you have the same amount of zoom range as would require over 15 pounds
of DSLR body + lenses. The P&S camera mentioned in the previous example is only
1.3 lbs. The DSLR + expensive lenses that *might* equal it in image quality
comes in at 9.6 lbs. of dead-weight to lug around all day (not counting the
massive and expensive tripod, et.al.) You can carry the whole P&S kit +
accessory lenses in one roomy pocket of a wind-breaker or jacket. The DSLR kit
would require a sturdy backpack. You also don't require a massive tripod. Large
tripods are required to stabilize the heavy and unbalanced mass of the larger
DSLR and its massive lenses. A P&S camera, being so light, can be used on some
of the most inexpensive, compact, and lightweight tripods with excellent
results.

6. P&S cameras are silent. For the more common snap-shooter/photographer, you
will not be barred from using your camera at public events, stage-performances,
and ceremonies. Or when trying to capture candid shots you won't so easily alert
all those within a block around, by the obnoxious clattering noise that your
DSLR is making, that you are capturing anyone's images. For the more dedicated
wildlife photographer a P&S camera will not endanger your life when
photographing potentially dangerous animals by alerting them to your presence.

7. Some P&S cameras can run the revolutionary CHDK software on them, which
allows for lightning-fast motion detection (literally, lightning fast 45ms
response time, able to capture lightning strikes automatically) so that you may
capture more elusive and shy animals (in still-frame and video) where any
evidence of your presence at all might prevent their appearance. Without the
need of carrying a tethered laptop along or any other hardware into remote
areas--which only limits your range, distance, and time allotted for bringing
back that one-of-a-kind image. It also allows for unattended time-lapse
photography for days and weeks at a time, so that you may capture those unusual
or intriguing subject-studies in nature. E.g. a rare slime-mold's propagation,
that you happened to find in a mountain-ravine, 10-days hike from the nearest
laptop or other time-lapse hardware. (The wealth of astounding new features that
CHDK brings to the creative-table of photography are too extensive to begin to
list them all here. See http://chdk.wikia.com/wiki/CHDK )

8. P&S cameras can have shutter speeds up to 1/40,000th of a second. See:
http://chdk.wikia.com/wiki/CameraFeatures Allowing you to capture fast subject
motion in nature (e.g. insect and hummingbird wings) WITHOUT the need of
artificial and image destroying flash, using available light alone. Nor will
their wing shapes be unnaturally distorted from the focal-plane shutter
distortions imparted in any fast moving objects, as when photographed with all
DSLRs. (See focal-plane-shutter-distortions example-image link in #10.)

9. P&S cameras can have full-frame flash-sync up to and including shutter-speeds
of 1/40,000th of a second. E.g.
http://chdk.wikia.com/wiki/Samples:_...%26_Flash-Sync without
the use of any expensive and specialized focal-plane shutter flash-units that
must pulse their light-output for the full duration of the shutter's curtain to
pass slowly over the frame. The other downside to those kinds of flash units is
that the light-output is greatly reduced the faster the shutter speed. Any
shutter speed used that is faster than your camera's X-Sync speed is cutting off
some of the flash output. Not so when using a leaf-shutter. The full intensity
of the flash is recorded no matter the shutter speed used. Unless, as in the
case of CHDK capable cameras where the camera's shutter speed can even be faster
than the lightning-fast single burst from a flash unit. E.g. If the flash's
duration is 1/10,000 of a second, and your CHDK camera's shutter is set to
1/20,000 of a second, then it will only record half of that flash output. P&S
cameras also don't require any expensive and dedicated external flash unit. Any
of them may be used with any flash unit made by using an inexpensive
slave-trigger that can compensate for any automated pre-flash conditions.
Example: http://www.adorama.com/SZ23504.html

10. P&S cameras do not suffer from focal-plane shutter drawbacks and
limitations. Causing camera shake, moving-subject image distortions
(focal-plane-shutter distortions, e.g.
http://images3.wikia.nocookie.net/ch...istortions.jpg
do note the distorted tail-rotor too and its shadow on the ground, 90-degrees
from one another), last-century-slow flash-sync, obnoxiously loud slapping
mirrors and shutter curtains, shorter mechanical life, easily damaged, expensive
repair costs, etc.

11. When doing wildlife photography in remote and rugged areas and harsh
environments; or even when the amateur snap-shooter is trying to take their
vacation photos on a beach or dusty intersection on some city street; you're not
worrying about trying to change lenses in time to get that shot (fewer missed
shots), dropping one in the mud, lake, surf, or on concrete while you do; and
not worrying about ruining all the rest of your photos that day from having
gotten dust & crud on the sensor. For the adventurous photographer you're no
longer weighed down by many many extra pounds of unneeded glass, allowing you to
carry more of the important supplies, like food and water, allowing you to trek
much further than you've ever been able to travel before with your old D/SLR
bricks.

12. Smaller sensors and the larger apertures available at longer focal-lengths

recordings, so that you might capture those rare events in nature where a
still-frame alone could never prove all those "scientists" wrong. E.g. recording
the paw-drumming communication patterns of eusocial-living field-mice. With your
P&S video-capable camera in your pocket you won't miss that once-in-a-lifetime
chance to record some unexpected event, like the passage of a bright meteor in
the sky in daytime, a mid-air explosion, or any other newsworthy event. Imagine

other important shooting data) directly on your electronic viewfinder display
you are also not going to guess if your exposure might be right this time. Nor
do you have to remove your eye from the view of your subject to check some

truly what you get. You won't have to guess in advance at what shutter speed to
use to obtain those artistic effects or those scientifically accurate nature
studies that you require or that your client requires. When testing CHDK P&S
cameras that could have shutter speeds as fast as 1/40,000th of a second, I was
amazed that I could half-depress the shutter and watch in the viewfinder as a
Dremel-Drill's 30,000 rpm rotating disk was stopped in crisp detail in real
time, without ever having taken an example shot yet. Similarly true when
lowering shutter speeds for milky-water effects when shooting rapids and falls,
instantly seeing the effect in your viewfinder. Poor DSLR-trolls will never
realize what they are missing with their anciently slow focal-plane shutters and
wholly inaccurate optical viewfinders.

20. P&S cameras can obtain the very same bokeh (out of focus foreground and
background) as any DSLR by just increasing your focal length, through use of its
own built-in super-zoom lens or attaching a high-quality telextender on the
front. Just back up from your subject more than you usually would with a DSLR.
Framing and the included background is relative to the subject at the time and
has nothing at all to do with the kind of camera and lens in use. Your f/ratio
(which determines your depth-of-field), is a computation of focal-length divided
by aperture diameter. Increase the focal-length and you make your DOF shallower.
No different than opening up the aperture to accomplish the same. The two
methods are identically related where DOF is concerned.

21. P&S cameras will have perfectly fine noise-free images at lower ISOs with
just as much resolution as any DSLR camera. Experienced Pros grew up on ISO25
and ISO64 film all their lives. They won't even care if their P&S camera can't
go above ISO400 without noise. An added bonus is that the P&S camera can have
larger apertures at longer focal-lengths than any DSLR in existence. The time
when you really need a fast lens to prevent camera-shake that gets amplified at
those focal-lengths. Even at low ISOs you can take perfectly fine hand-held
images at super-zoom settings. Whereas the DSLR, with its very small apertures
at long focal lengths require ISOs above 3200 to obtain the same results. They
need high ISOs, you don't. If you really require low-noise high ISOs, there are
some excellent models of Fuji P&S cameras that do have noise-free images up to
ISO1600 and more.

22. Don't for one minute think that the price of your camera will in any way
determine the quality of your photography. Any of the newer cameras of around
$100 or more are plenty good for nearly any talented photographer today. IF they
have talent to begin with. A REAL pro can take an award winning photograph with
a cardboard Brownie Box Camera made a century ago. If you can't take excellent
photos on a P&S camera then you won't be able to get good photos on a DSLR
either. Never blame your inability to obtain a good photograph on the kind of
camera that you own. Those who claim they NEED a DSLR are only fooling
themselves and all others. These are the same people that buy a new camera every
year, each time thinking, "Oh, if I only had the right camera, a better camera,
better lenses, faster lenses, then I will be a great photographer!" If they just
throw enough money at their hobby then the talent-fairy will come by one day,
after just the right offering to the DSLR gods was made, and bestow them with
something that they never had in the first place--talent. Camera company's love
these people. They'll never be able to get a camera that will make their
photography better, because they never were a good photographer to begin with.
They're forever searching for that more expensive camera that might one day come
included with that new "talent in a box" feature. The irony is that they'll
never look in the mirror to see what the real problem has been all along.
They'll NEVER become good photographers. Perhaps this is why these
self-proclaimed "pros" hate P&S cameras so much. P&S cameras instantly reveal to
them their ****-poor photography skills. It also reveals the harsh reality that
all the wealth in the world won't make them any better at photography. It's
difficult for them to face the truth.

23. Have you ever had the fun of showing some of your exceptional P&S
photography to some self-proclaimed "Pro" who uses $30,000 worth of camera gear.
They are so impressed that they must know how you did it. You smile and tell
them, "Oh, I just use a $150 P&S camera." Don't you just love the look on their
face? A half-life of self-doubt, the realization of all that lost money, and a
sadness just courses through every fiber of their being. Wondering why they
can't get photographs as good after they spent all that time and money. Get good
on your P&S camera and you too can enjoy this fun experience.

24. Did we mention portability yet? I think we did, but it is worth mentioning
the importance of this a few times. A camera in your pocket that is instantly
ready to get any shot during any part of the day will get more award-winning
photographs than that DSLR gear that's sitting back at home, collecting dust,
and waiting to be loaded up into that expensive back-pack or camera bag, hoping
that you'll lug it around again some day.

25. A good P&S camera is a good theft deterrent. When traveling you are not
advertising to the world that you are carrying $20,000 around with you. That's
like having a sign on your back saying, "PLEASE MUG ME! I'M THIS STUPID AND I
DESERVE IT!" Keep a small P&S camera in your pocket and only take it out when
needed. You'll have a better chance of returning home with all your photos. And
should you accidentally lose your P&S camera you're not out $20,000. They are
inexpensive to replace.

There are many more reasons to add to this list but this should be more than
enough for even the most unaware person to realize that P&S cameras are just
better, all around. No doubt about it.

The phenomenon of everyone yelling "You NEED a DSLR!" can be summed up in just
one short phrase:

"If even 5 billion people are saying and doing a foolish thing, it remains a
foolish thing."
