The full shots both look fine from both cameras but the 100% crops clearly show that the new K-5 is playing on a whole new level.
Pentax has stepped into a new league.
The K-7's black readout noise, even at ISO100 always irritated me. It was fine with any ligher coloured surface , but when the surface is black, or is in deep shadow, the K-7 always had luminance noise even at base ISO.
Looks a lot improved in the K-5
My K-5 arrives next week

Something that is not observable in the images is the fact that the K-7 (like the K10 and 20 before it) chews on the images for a *long* time before you can use the camera again. The K5 doesn't seem to do this at all. I guess this is because the other bodies are doing post processing in the body?
The K-5 allows Forced DFS (Long Exposure Noise Reduction) to be turned completely off - which was not possible with the K20D and the K-7 for exposure longer than 30 secs.
