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!


Do you know...I had forgotten it was only 20mp. Got it in my head it was 24mp. :doh:

Am afraid I haven't mastered BIF yet. :needsahug:
