Nikon D850
Whether or not the D850 is even on your radar is largely dependent on how vested you are in your current camera system, and whether or not that system is Nikon. Let's talk about other systems first. For Canon devotees, we recommend the EOS 5D Mark IV in the professional full-frame class.
Full-frame 45.7MP image sensor; 153-point autofocus system; 7fps burst shooting; Wide ISO range; 4K video; Large optical viewfinder; Tilting touch LCD; Dual card slots; Bluetooth and Wi-Fi
Live View focus uses contrast detection only; Omits built-in flash; SnapBridge system needs some work
