This is an apples to oranges comparison. And it will remain that
regardless of how much processing you do. If you want to compare the
cameras, do a controlled test. However, I would be surprised if the
K20 wasn't considerably better. Mine K20D was light years less noisy
than my *istD and a lot better at rendering color in AWB mode.

If you're shooting JPG, why bother with a grey card??? Kinda like
buying a K20 or K7 and never moving the mode dial out off the
"green" zone.
I don't (deliberately) shoot JPG.
The whole point of using a grey card is to correct colors in RAW
files. One can't correct JPGs very much, or very accurately.
Exactly, whichi is why I almost always shoot RAW.
The main difference I see is the sickly green cast in the K100
shots versus very strange colors under various colored lights in
the K20 shots.
I tried to get a first approximation by using the custom white balance
in the camera. Lightroom used that as the default when converting the
RAW to JPEG.
I wanted a quick sanity check to see if my gut feeling that the K20
wasn't performing up to snuff was accurate, so I Just tossed the
really bad photos and did a quick conversion on my way out the door to
work this morning.
No meaningful comparison possible.
I was afraid of that. I hope to get a chance to spend some time on
them, and post the more heavily processed shots, likely in black and
white. Eventually, I'll have to do some side by side tests, preferably
with another K20.
(Was that a Wheatfield-toned post, or what??)
What is Wheatfieled-toned?
Cheers,

I've had the gut feeling that the
image quality of my K20 isn't up to
par. As a matter of fact, in low light situations, it my
not even be
as good as my K100.
I did an informal test, shooting with both cameras at a
dance Friday
night. The K20 was shot at 3200, 1600 and 800. The
performance shots
were taken at 1600 with a flash
The K100 was shot at 800, pushing it a stop or two in post
processing.
The only processing done to the shots was throwing away the
totally
bad ones and "auto tone" in lightroom, with a couple of the
"pre
greycard" shots white balanced, most of the shots are in
camera custom
white balance. They were all shot raw and processed to
1000x800 in
lightroom.
These are the two sets. Comments on the photography are
welcome, but
would more reflect the lack of editing, comments on the
apparent
relative performance of the cameras is solicited.
I used the same lenses (31, 50, 77 and maybe 40) on both
cameras,
mostly at f/1.8 or thereabouts. I mostly used the 50 and
the 77. If
you're curious, check the EXIF for details.

The first step is learning to take great photos,
the second step is learning to throw away ones that are
merely good.
