Sigma SD10 Web Site Update
 

The Sigma SD10 Information Site has been updated. http://sigmasd10.com is
the authoritative site for unbiased information about the pros and cons of
the Sigma SD10 digital SLR.

This was a minor update.

1. A little more information was added on the cause of the color rendition
issues with the Foveon sensor.

2. Changed the 27 links of the definition of a pixel into numbered links,
rather than the entire URL.

3. Even though the R-CRV3 Li-Ion option isn't on Sigma's web site yet, I
went ahead and changed "No Poor Rechargeable Li-Ion Battery Option," to
"Poor Rechargeable Li-Ion Battery Option."

4. Added links to other reviews of the Sigma SD10.

If you find any errors or omissions on this site, please let me know. I have
made several changes as a result of feedback from rec.photo.digital
contributors.

I see nothing new there about the SD10. The photos I have seen, taken with
it have all looked quite good. The only problems I'm aware of (which would
stop me from buying this or any camera) a

1. The SD10 has a propensity toward accumulating dirt behind the dirt-shield
on the sensor.
2. The SD10 uses solely Sigma lenses.
3. Sigma lenses seem (from the lens Jeff used in his review) to have unsharp
patches (bit more grinding needed).
4. The SD10 uses RAW format as opposed to JPEG and that could cause serious
difficulties.

I do like the Foveon sensor but that's the only thing I like about this
camera.

I dislike tremendously the tri-sensor arrays of the current digital cameras
because of the way they can cause moire problems and because all images are
interpolated and are therefore inherantly unsharp. What we get (crudely)
when we buy a 3mp camera is a 1mp camera with interpolation.

ah hah hahah ha heh heh heee

lol

nothing like a good flaming is there - quiet weekend?

Nah then - I've looked for a couple of moments and first techie faus pas
(IMHO) is sensor outputs an image Que? What? Run that by me again?

so I can plug in the sensor without any supporting hardware or software and
see an image?

For any1 new to the forum - it's an ongoing metaphysical thang yo'all

I think you may need to revisit what a pixel is

nah then, even more important The Gimp

watcha know?

i should be more serious - heh heh heh

a sensor (IMHO) outputs data
that data goes to an analogue to digital converter (usually acronymed to
ADC)

when an image of 3.4MP is displayed on an output device it may be in one to
one correspondence with the data supplied by the sensor nothing more
nothing less

inbetween there is quite a lot of digital signal processing

digital signal processing and a sensor (any sensor) have limitations and
constraints inherent to the method of manufacture and some of the
consequences are that the attempt to accurately capture images means that
the data and data processing actually introduce corruptions that make the
final output display (or print) subject just a little bit dodgy

some of these corruptions may be tweaked however, as has always been the
case in photography, attempts to improve one aspect of an image introduces
corruption in the form of image artefacts or degradations elsewhere in the
output image

There is a great deal of sophistication in hardware, software and firmware
used to optimise image quality

i think i shall stop there

ps - a sensor outputs an image? a hah hah hah haaah

hmmmm - something is beginning to make sense

first of all it was the one to one correspondence of JPEG images (image is
optimised by displaying the image at the resolution chosen when the JPEG was
created. That is what the JPEG spec is there for)

Whatever the flaming criticism paranoia expressed in the NG the Foveon
sensor does have something going for i.

Why, for example, should a 3.4MP Foveon image be almost comparable to a 6MB
or 8MP canon image?

Doesn't it make sense to have similarity of output image for one-third to
one-quarter of the umage output file?

Of course it does!

I think (thios is all IMHO) the thing going for Foveon sensors and
technology is that it maintains a one to one ratio between sensor f=data and
output image (c) just in case marketing bods are reading this - you may
follow the topic introduced here but accreditation to & permission from das
B first if you please :-)

No, the reason Foveon is creating shock waves is because maintaining a one
to one correspondence seems to minimise artefacting and degradation.

Before the flaming starts (a flamed bagal anyone? lol) similarity of image
quality at gross diversity of sensor imaging elements? Hasn't the penny
dropped yet?
