is trying to do to the Sigma image somethink close to what Canon is
doing to your Canon pictures before you see first time. This is
fair.

The siimilarity of this two pictures is very high
remarkeble because it is a two years old Foveon with 1 year history
compared to the newest Bayer after several years tuning and
improvement of this technology.

More on
the software postprocessing could be better (for Sigma)
is not the same lens (The canon is proberly better)
the studio setup could inflorence etc.

You can NOT make a fair comparetiv test by downsize the Canon and
then sharpen it. But you can downsize both - sPavels Sigma back to
normal size - and the sharpen both of them. It will tell you what
you can do to the images after the first postprocessing - visible
(Sigma) as well as invisble (Canon).

But Canon 20d is a beautifully camera with perfect images comming
out instantly - in most condition - fast and with a big buffer.
Sigma should be proud that it is worth testing at all.

I think to most people the 20d in a pragmaticaly test would make
the sharpest images. In some special pro and semipro 6*6 alike
condition Sigma will maybe be superior due to the razer sharp
un-postprocessed images not availble to Canon.

It's digital, it's all postprocessed.

Nope the Sigma images are not interpolated-sharpen/postprocessed when they are comming out of the camera!!

If you do the same to a Sigma image (in a software program) that the canon camera does to a Canon image you will get allmost the same result. That is what Pavel Sokolov has shown.
Nice photo btw

these test confirm atleast
to me that their is no significant sharpness advantage to the
foveon sensor, unless they come out with a 6mpx3 or 8mpx3 sensor
then people will just buy the 20d with an 8mp cmos, great
iso400-1600, great auto focus, superior glass available and 5fps if
you need it. If you want foveon sharpness then just resize your
images to 2268x1512 and sharpen them using photoshop.

Maybe unless Sigma makes a 10b cretaing interpolated and sharpen e.g. 9 mp Sokolov pictures direct from the camera (like Canon) and a lot of people therefore will think it is sharper.

(I only disagree re the resolution - the rest I've no knowledge about but I believe you)

look razor sharp and from an outdated digital rebel. Oh wait it
was post-processed so it isn't fair. :^(

here's the canon image resized to the native resolution of the
sigma which is superior in sharpness to anything by default. I
sharpened the canon image, no need to sharpen the sigma right? I'm
going to be sorry to see this post hit 150. I can't wait for the
next comparison.
