Also I must add that the k-5 does some definite noise reduction to the raw files over iso 1600, whether that's in the imaging pipeline or the firmware is neither hear nor there at this point. At 3200 on the k-5 you are most certainly trading resolution for image quality. I don't have any real figures, but I feel that looking at the files from my k-5, its easily giving up quite a bit of resolution due to noise smoothing. From what I can gather the K-3 is resolving more fine detail but yet showing similar amounts of noise when resized to k-5 resolution. That's what I have seen with my own eyes at least. To be honest they are pretty close and careful raw processing will result with more detail in the k-3 files with similar noise levels. I find pentax's jpeg engine to be not the greatest at noise reduction, but honestly, its better than some other camera makers too.
