Nikon D850 Review

The D850 solved a problem the industry had accepted as permanent: you chose resolution or you chose speed. Nikon put a 45.7 megapixel back illuminated sensor into a body that shoots seven frames a second, handed it the autofocus module from the flagship sports camera, and kept the optical viewfinder, the two card slots and the battery life that let a wedding photographer work all day without hunting for a charger.

Low sensitivity dynamic range is the best any full frame sensor of the era measured, files survive heavy shadow lifting without falling apart, and the tilting touchscreen and illuminated buttons show a company that had been listening. Weather sealing is the kind you stop thinking about. Video is the honest weak point. Full width 4K at up to thirty frames is genuinely useful and better than any Canon reflex offered, but there is no log profile in the camera, and live view focus is contrast based and slow enough that manual focus is the only reliable approach to a moving subject.

Mirrorless bodies have long since passed it on tracking and on silent shooting. None of that has persuaded owners to sell. For anyone who wants an optical finder and one camera that does everything, the format ends here and it ends well.
