So I have read alot of the comments essentially it comes down to what you shoot landscape go get your nikon 800, action get your canon 5d mk111. the 5d Mk 111 a ff 7d it is a much better camera then a 7d I have owned both. First full frame canon I want two of. They really are cameras for different pruposes so get over it. There is no right answer for everyone. What you shoot determines what you buy. David
