All the K-X people are putting the hurt on us Non K-X owners.
Since I just recently posted yet another K200D vs K100D comparison over on dpreview, I figure I might as well post something here too. No, not the shot of my bare foot I made folks endure over there, but rather, something people might actually like.

K200D, ISO 3200 (push processed equivalent):

A few more...

Another ISO4000, in very low light(notebook screen).



A ISO3200 off my desk.
Taken for another discussion, but it shows what the K20D can do(very clean).



And a crop

First attempt at High ISO shots

I just wanted to post a picture (1 of about 250) that I took a couple of weeks ago at night - a Snowboarding superpipe in Michigan - training for Olympic snowboard teams. This first picture was unprocessed - taken with the "noisy" Pentax K-7 with a 50-200mm WR zoom at 1/160 sec , F5.6. - ISO 6400. The second is after using Noiseware Community edition. This was my first try at highspeed shooting and high ISO shots.

Marc, sorry I missed the shot of your, er, barefoot--but I really am enjoying this very nice shot @ 3200.

Really nice work with the K20--especially good use of the notebook light. I really like my K20 @ 3200 too. Just one personal question though, how much did Giotto pay you to post these shots. LOL

K7 High ISO shots

Here are some photos made with my K7 and 35mm 2.8 LTD lens at dusk. The first one is ISO 2000, the rest are at ISO 3200. All were shot RAW and produced with Lightroom 3 beta, using a small amount of chroma noise reduction. (Luminance NR is disabled in the LR3 beta, so what you see is what you get here).

Patrick,
To be honest, these show a ton of noise and these are small images. Am I missing something here?

It's the dreaded banding that seems to affect these shots the most.
Its very hard to manage in NR and can be quite prominent on some camera's in contrast to others.
I don't know if the banding is the worst of the issues brought on by the K7 at ISO3200 though.
because color blotching to be fairly prominent as well.
But the banding sure can't help in the end.

For what it's worth, we have two K20's, and one of them has worst banding than the other.
Though the worst of the two has the later firmware, I refuse to upgrade old trusty just in case that it's performance is somehow tied into that.

I agree with you and have been saying as much. I also have two K20DS with the latest firmware and walk circles around my K-7 in the high ISO dept.

My Daughter

Shot with K20 at iso 3200, using DA 70, at f2.4 and 1/20 second. Pretty aggressive vertical crop of a horizontal photo.

Maybe, the A/D converter needs to be "burnt in."

But seriously, those shots look like poorly calibrated inkjet printer printounts. After looking at so many examples, the pattern noise is beginning to grow on me...like fungus on a lens.
