I just noticed this thread. I can say as I had wondered before, the IIs has less, or at least smaller, noise grain. Maybe this is just each pixel not bleeding over to the next, but the appearance is of less noise. Maybe the lack of a standard LPF blocks less actual light and allows for less iso gain? I would be interested to know exactly why this is, but there is a definite difference. I will also say, the original K5 looks slightly worse than the II, and the II looks slightly worse than the IIs.

It's hard to compare the K-5 to either of the K-5 II(s) as the 'II''s are focussed a little further frontward than the K-5, which seems to be focussed on the background surface.

I guess this is as good a time as any to get into it. I have also heard from people that uneven focusing makes these comparisons worthless, but in reality it is only that way for sharpness comparisons. A camera will show the same noise profile whether you are tac sharp or not. This is a very simple example, two shots, one almost focused on a wall with a nail, and one totally blurred. Crops were cut from the full size file, then up rezzed for easier viewing. Full FOV files are downsized to show the difference in focusing of the two. The crops are taken from the portion just to the left of the nail. In terms of noise, both are identical, focusing makes no difference in noise pattern.
