Do you have data for Exmor sensors outside Nikon cameras? I suspect that the K-5 exhibits similar behaviour, though it's difficult to say because there is noise smoothing above 1600.

I haven't investigated any camera models which I do not own (or plan to own), so the K-5 is an "unknown" to me. At the risk of opening Pandora's box (I already spend too much time on the Nikon bodies), I suppose I could have a look.

My own guess is that the column capture chain is pretty configurable, with programmable gain stage(s) (obviously). It would be possible for Nikon to make quite a few optimisations in the programming.

I think that explanation fits well with what we're seeing.
