Frank, I see a color color moiré in your D500 sample that I'm sure could be removed in CaptureNX-D's Camera and Lens Corrections pallet. I see this in my D800 files at a lower ISO. The C&LC pallet is bottom, second to left in the Edit section on the right side. I think if you try it your high ISO sample with be even more impressive. I'm jealous. Dave
Thank you very much, Dave, for the hint. In the beginning it was very difficult for me to do proper edits of the D500 files. I come from the relatively soft D600 files which can bear a lot of abuse in post and the D3 files which are relatively low res anyway. The Pixel Density of the D500 would be roughly 45 Megapixels on FX.
So to retain the super rich details I can get from the D500 with good light, good glass and good technique, I have to apply all contrast and sharpening very sensitively.
If I run in fast mode editing a lot of pictures in a short time, I sometimes tend to not zoom into 100% but edit for the impression I see in the downsampled, resulting in oversharpend pics with too much contrast.
The D600 files at high ISO are worse than the D500 files!
At low ISO I still like the tonality of the D600 better esp when it comes to flowers and human skin
