I have both cameras in black, bought years ago really cheap. The F had a Photomic FTn, but now I have the standard prism. I hardly ever use the cameras, too heavy and too noisy.
I prefer the rangefinder Nikons, above all the S2. But the F and the Nikkormat FTn never give up. The Nikkor-S 50mm f2 is said to be better than the Nikkor-H 50mm f2. The H-f2 has some distortion, but the S-f2 is said to have straight lines. I never tried the S.
I love the looks of these cameras. I have a black S2 and it is surprising how much the three cameras have in common. In my eyes no later Nikon looks as nice as the S2, the F or the Nikkormat FTn - in black, that is.
