K10D vs K7 High Iso

I happen to do a fair amount of shooting at higher ISO but I limit high ISO shooting with my K10D to 800 due to noise. I've read all the complaints about the high ISO performance of the K7. What I'd like to hear is a comparison of ISO800-1600 images between K10D and K7. I'm thinking of getting a K7 because of all of the other improvements over the K10D (auto focus speed, fps, etc...) but how does high ISO stack up in the real world as opposed to pixel peeping?

The K-7 has similar high ISO as the K20D. So all you need to do is look at K20D high ISO and there you have it.

I don't have any experience processing photos out of a K20D but I know my K10D quite well having used it for over 2 years, hence my request for info on the K7 vs. K10D.

Here's one K10D/K20D example:

ISO 1600

If my memory is correct most reviews seemed to think that you got about a 1 stop advantage with the K20D over the K10D. So ISO 1600 on the K20D looked similar to ISO 800 on the K10D.

Thanks. I think I used LeDave's response in a roundabout way to answer my question using this thread:

K7 is approx. equal to K20 and K20 is superior to K10, therefore K7 is better than K10. That's good enough for me.

K-7/K20D are significantly better than K10D. Shoot in low light with both and you'll be quicky convinced of it.

I have a K20 and am not happy with it at the highest ISO. I recently shot some test images with a K7 using the same settings.

I was not impressed with the results. It was about the same as my K20. And that is also the feel here from the other threads I have read.

FWIW, I could only stand ISO400 on my K10D. I leave autoiso set to ISO800 on my K20D but if you set ISO manually, you can set it to ISO1100 w/o any real difference (autoiso only works in full stop increments or I'd leave it at ISO1100)...
You'll like the upgrade...

With my K10d I had times when at floodlit football (soccer) matches where I could not get any usable images.

With the K7 I am getting very nice images of the action under floodlights. Loving the K7. It is awesome.

Auto ISO works on full, half or third stops. I don't have my K20D with me to tell you which line item, but look in the Custom menu and you'll find it.

Maybe it's just me, but I find the K10D quite usable at ISO 800-1250, and even up to 1600 under certain circumstances. Especially with the new lightroom, which handles chroma noise beautifully. Honestly, if it weren't for the K-7's film-like video, 100% viewfinder, and hard ISO button I probably wouldn't be interested in upgrading.

The ones not happy at 1600, honestly, are you printing at 11*14 or 16*20regualrly?
