The overall performance of the D850’s sensor rivals the Phase One IQ180 and Phase One P65 medium format cameras. While the high-res of the D850 gets in the way of the low light performance at higher ISO settings, it still manages a very respectable showing in that department as well.
The D810 proved a fantastic win in the image quality department. And generally, Nikon sensors have done very well on DxOMark tests. While not a direct competitor to the Canon 6D Mark II, news of the D850’s historical test results are a bit of a black eye to Canon in the wake of the Canon 6D Mark II’s woeful performance.
