Originally posted by j2photos I bought a K-3 last night myself. I think it is, everything I have seen the AF system is leaps and bounds better. While the pictures may be a hair more noisy than the K-5 series the K-3 holds detail FAR better. The AWB seems to be spot on, it shoots faster in burst... I am not coming from a K-5 I am coming from a K-7 so this should be a substantial upgrade for me.
Shame it's a bit noisier with a tad less DR, but the rest of the package looks interesting, especially for those using screw-drive lenses and for manual focus.
Topaz DeNoise in CS6 should sort the files out.
