A:Answer7200 is crop frame DX camera, 850 full FX, so I’m not sure if 850 has a mode to adjust for using as such. Suggest check Nikon web site for 850, should have compatibility lists available.
A:AnswerThe Nikon D850 and the D780 are two completely different cameras that each have their own specific features to help with different types of photography or video needs. The D780 will act much like our Mirrorless Z6 camera when used in the Live View Setting. It has the advantage of using the phase detect focusing system while having added focus features like Eye-AF. While both of these cameras can shoot in 4k UHD, the updated focusing system also helps the D780 excel when recording video. The D780 also has a higher native ISO than the D850, being able to go up to 51,200, compared to the D850 being able to go to 25,600.
