Excellent progression of the Nikon professional line
As a long time Nikon photographer, from the earliest Nikon Fs to my latest addition of the D850, each model brings something more to the table. My Nikon F and FTNs still work excellently, as do my original Nikkor lenses from the early 1960s! I have had some concern as Nikon started manufacturing and producing outside of Japan, but fortunately, the quality seems to be maintained. The increased resolution of 45.7 megapixels of the D850 along with the tilting touchscreen make it my primary camera across all of my work, I really like working with it along side of my D810, having a fixed length lens on one and a zoom on the other. The D850 focuses a bit faster as well.
The D850 IMO makes it easier to capture the image you ´see in your mind´ as you look at your subject. It is a well designed, highly functional camera.
