I want to buy an autofocus Nikon body. I have an N80 with the MB-16 grip and a bunch of Nikon AF lenses. I'm thinking of either the F100, F5, or F6. Obviously, the prices vary wildly. Can anybody justify the extra cost of the F6 over the F5? For that matter, can anybody justify the extra cost of the F5 over the F100? I'm a street shooter and wide angles are my lenses of choice. I like the silent modes on the better Nikons because I'm usually close to my subjects and I'm very nervous about the SLR's noise. I've got a Bessa L and a 15mm Heliar, but I miss the ground glass viewing of the SLR. BTW, the N80 is one of the most quiet Nikons I've ever used.
