Default Factor Effecting High ISO Pictures - Camera or Lens

You idiot, the person you are replying to never claimed a smaller sensor made of
the same materials and the same design and manufacturing process would have less
noise per equivalent number of pixels. Though the newer small sensors do indeed
surpass earlier larger sensors in noise levels. You can't make blanket claims
like you continually enjoy doing without taking into account advancements in
materials, design, and manufacturing methods. But then you just love sticking
your stupid head in the sand (or is that your ass? it's so hard to tell with so
much sand up there) and trying to cover up your tracks with misinformation.

The person you replied to claimed that the total capabilities of the P&S camera
far exceed the capabilities of any DSLR for less money. ONE extra f-stop in ISO
performance (minus the phenomenal zoom range in any of the UZ P&S cameras) for
an extra $2,700 does not a sale make. Anyone paying that much money for just
1-stop increase in performance with all the drawbacks of an interchangeable-lens
system has several screws loose.

Get with the program dude. Or at least learn to read what you are replying to --
before using it for another or your many excuses to post your lousy spam-site
URLs.


You can keep changing your name, but your ...unique writing voice stands
out loud and clear.

And despite what they might say on the box, ISO800 on a superzoom camera
is a joke. On my FZ5, which is a 5 MP camera (ie bigger pixels than the
newer 7 or 8 MP models), I'd go above ISO 200 only in a dire emergency
or if I knew that the picture was going to get drastically downsampled.
At 400, the full resolution pictures were very noisy.

That was precisely one of the reasons why I recently shelled out the
money for a Nikon D80; now I can go up to 1600 without much trouble, and
3200 if I absolutely need to.

If I had enough $$$ I would replace both, but since I have only
limited resource - I am trying to figure out which would give me more
bang-for-buck.


I'm looking at the 24-70mm AF-S Nikkor and also the D300 as
prospective candidates. Each run about $1,700-$1,800.


The D300 body will buy you better low light performance than the lens
upgrade. That said, consider the options below as a general upgrade path.

The D50 has pretty goodhighISOperformance. The D300 does go to a
higherISOand with more megapixels. The 24-70mm f/2.8 AF-S is only
faster on the long end so not very different. Where you'd get more bang
is with an 85mm f/1.4 prime lens for $1,000 and a 50mm f/1.8 for $100.
Of course that means more changing of lenses but it will be an overall
significantly better lens. Do be aware that the faster f/stop means more
shallow depth of field. Also consider that the 24-70 f/2.8 AF-S is a
much better lens than your 24-85 f/2.8-4 even though it isn't much
faster, it is actually sharp wide open at all focal lengths. Another
factor is Nikon seems to be moving to AF-S compatibility only on their
consumer bodies so that won't AF on a D40 for example.

I would say go for the 24-70 for improved image quality but it's not
going to improve low light ability much... for that you will need a
faster prime lens and the 85/1.4 fills the gap at the end where your
lens is slower. The D300 body actually will probably improve low light
performance more but really the lens is the more important part of the
package for image quality.

Thanx for the explanation. Actually, I do have a 50mm f/1.4 lens which
I use occassionally. But the 24-85mm zoom really comes handy (though I
know I'm paying in picture quality).

I think I'll get the 24-70mm lens first (soon) and then, maybe, the
D300 (next year??) and then the 85mm. I have used the 60mm (http://
flickr.com/photos/smriti/tags/60mmf28/) in the past and have been
meaning to get the 60mm, 85mm or 105mm at some point anyway.

I also want to move away from the D lenses, because one of these days
I really hope to get a Full Frame Sensor camera body like the D3
(right now it's in my dreams, but maybe one day I'll actually be able
to afford it)

I really appreciate all of your helpful suggestions.

Don't get rid of the D lenses - they will work perfectly fine on a D3 (or on
any Nikon DSLR/SLR) - except for AF on D40/D40x.
