Originally posted by joe.penn I don't know - if going by just the snaps above it appears the noise on the K5 image is smeared (by NR). It looks like that maybe 2 different procedures/NR Alg's were used for each image.
In any case, there is one thing to be said here - NIKON is on the ball in the DSLR realm at the moment with all of their recent and recently rumored releases, they have come out of the gate in full stride, impressive to say the least!
Comparing the JPEG high ISO shots is straight from camera, and the k-5 version has NR turned on. My understanding is that the k-5's jpeg output at high ISO isn't so great - and a lot of review sites gave it flak because they never bothered to look at the RAW.
In fact, if you look at the RAW processed ISO 3200 shot of the k-x, it beats the out-of-body jpeg from the k-5. But once we talk about RAW files, the k-5 is king of this bunch (of course), and the k-x still beats the D3200. The D3200 just has a larger resolution - it has so much more noise than the k-x.
At ISO 100, the D3200 looks lovely. So yes - it's a great sensor. But even at ISO 800, you are getting quite a bit more chroma noise. And chroma always looks uglier than luminance noise.
