Thank you for the reference to the links.

When looking at the PDR.htm chart above. Choose K-1 and K-1 II then you see that something strange happens at ISO 636. The PDR improves with 1.66 stops. At lower ISO they are identical. But, from 636 and up, the mk II is 1.5 stops better or so. And this is pure noise reduction. Nothing else.

Same thing happens here at ISO 636.

This noise reduction is not possible to turn off. So, as a photographer you hope that you do not find situations where you really would like it.

I know that astronomers really dislike noise reduction in the RAW data. One example is the infamous Nikon star eater. But even if stars are not eaten, noise reduction destroys the statistics.

So - how about us less celestial photographers. Is this mk II noise reduction in any way bad? Personally, I have not the slightest idea.
