Originally posted by Marc Sabatella I assume you are aware of this, but in case not - basically the only reason the K20D has less noise at high ISO is that it does more NR in camera. This has been measured empirically. You should be able to match its results with the K-7 by doing the equivalent NR in PP.
Thanks Marc - I had read something like that, and I appreciate the info... I think perhaps my problem is that I shoot exclusively RAW, and until now have relied on Lightroom 1.4 for all my processing - perhaps it's time I try a different NR software (first I see if an upgrade to Lr 2.* will handle the noise better - just gotta download the demo...) I love the K-7, but I'm really hating the results I get above around ISO 640 or so. It's not just noise, but the noise seems blocky - like the noise "grain" is four pixels big rather than one, and these large grains are scattered here and there rather than continuous. When I crank the NR in Lr it looks pretty good for the most part, but there are these blocky artifacts here and there... I'll look into it more - I'm not giving up yet
