Eric, what ISO are you using on the D500 when you get noise? I dont see this with my D500 but I dont have to boost ISO. My D500 is in UK so I cant test easily but I can look through images.

The visible noise of which I speak is a function of how much cropping I have to do when photographing distant birds.

The full picture may be perfectly 'noise free' to the eye at 2000+ ISO ...but crop in to (say) quarter frame and artefacts cane be seen.

I believe Graham has noted that his D850 ( being a FF sensor) has on balance less noise at high ISO than his D500. I have no experience of the D850 but I sometimes feel the heavy cropping combined with the higher ISO needed to use fast shutter speeds with birds in U.K. would benefit from anything that's on offer.

Of course a longer lens would be another answer...so roll on the 500P


Definitely agree with your comments wrt to enlarged hi ISO images that are cropped.
It is the reason I got the Nikon 200-500, cropping is still required for some BIF images which really shows what you describe, D500 is only 20MP!
