Originally posted by tbirdas Even though I am seriously considering a K-5 myself, I have been getting very good low-light pictures at ISO 3200 from my K-x (with reasonably fast lenses -2.8). I'd be curious if anyone has a K-5 to K-x comparisons
That doesn't come as much a surprise. What comes to mind is the K-x was the Pentax body with a sensor that had a noise behavior which was by far the most mono-chromatic of all its predecessors (well, modern body; wasn't the *istD like that?), vs. the significant chroma noise the K10D, K20D and K-7 and others would produce. It led [most] everyone to say that sensor (or evolution of it) needed to be used in the K-7's replacement ... So you shouldn't lose sight of that fact or feel your K-x needs replacing; unless you want viewfinder focus feedback which is really the only negative I ever heard about that body.
