Colours and field may look fine, but this is just the centre of the heavily cropped frame.
I’m not sure how other users of the D810a handle the mismatch of the Nikon-F-type-connector and the D810’s full-size sensor (35.9mm x 24.0mm) that in my opinion is congenital (porthole-effect). I’d like to hear from others on this issue ...
