Yes, I think Bruce is right. Obviously, I didn't get a chance to, but it
would have been interesting to shoot in darker light. However, when I was
at GFM, I took a quick shot with the K7 @ 3200 one evening in the cafeteria,
which had quite dim light, and I remember being impressed--course then I
continued drinking and don't remember much else ;-). Seriously, though I do
remember being impressed with the K7. I also think that you can get some
good results with the K20 at high ISOs--not always, but I've had some good
results. Cheers, Christine

I forgot to post these. I tried the K7 at Central Camera a while back.
These were shot as jpegs, aperture priority, pattern metering, no
exposure
bias. These are 1200 pixels on the long end and fairly big files.
Shutter/aperture info is stated above shot. Just an FYI.

Interesting. That's a lot cleaner than what I've learned to expect from
K20D.
I've seen noise performance like that from the K20D, and darned close from
the K100Ds. The _critical_ thing is getting proper exposure. If you
tweak up any dark areas after the fact, the noise shows up. If Christine
were to play with the Fill Light slider, or had shot these down a stop and
raised it up, you'd see way more noise here.
So you *should* get relatively low noise like this from your K20, Tim. The
trouble I find is that in really dark rooms one tends to underexpose a
stop or two to keep the shutter speed high enough for hand-holding or
monopod use.
