I've recently bought the D500, doesn't have the resolution of the d810/d850 but it works fine as an action camera, actually it could be used for any subject I reckon. This Great white Egret was captured on a very dark morning at the end of a recent snow storm, d500 nikon300mmf4 pf & tc1.4 for just a touch more reach. I've since discovered the lens was front focussing by a touch when used with the teleconverter, made an in camera adjustment of +2, everything is fine now. focus was off by a fraction in this shot but it doesn't look too bad considering. cheers.
