Originally posted by JinDesu There were a few owners who made comments in the general k-30 threads running around. My memory of this include:

-The k-30's detail retention is a bit better than the k-5 at high ISO
Hopefully someone can clarify more.
From the DPR comparo tool, I have to say that the difference is slightly weaker, mostly negligible, in the K-30. The character is slightly different, mostly.
The chroma noise is better described as "different" in character. The K-5 wins out, though if you're looking to quantify it, but the fact of the matter is whether the character is something that your PP program can deal with or not. With LR3/4, I've preferred the K-5 character of chroma when dealing with it. It appears to leave nicer, cleaner pics behind with better detail.
The detail retention seems a bit interesting between them. It looks better in the K-30, but overall, fairly similar. I think that's a good thing, by the way. The K-5 is still a tough act to follow (and the D7000), so even if performance is the same, they are still great, not to mention, astounding for entry-level/intermediate cams.
