D7200 at 1.3x crop mode + Nikkor 800mm f5.6 ai-s EDIF + tripod;
ISO 1250, wide opent at 1/1250s. More cropping of an already cropped capture: 25% crop (7/24Mp).
Bad news: my virtually new (1600clicks!) D810 from nothing started to refuse recognizing both MF (including chipped ones!) and AF-D lenses
It gives a blinking FEE and, yes, I put the lens at minimal f/ aperture;
But it works without problem with the 200-500E AF-S or 24-120/4 G AF-S. Do not know what was the problem! Has any of you guys heard of a similar issue like this one?
Fortunately the body is still within the 1 year warranty from the shop I bought it.
