I'm talking about feel. I'm interested in a MF Nikon and so I am thinking F-F3. Well I have an F with photonic head and it feels a bit clunky and so I am thinking of maybe getting a plain prism on an F2 or maybe just an F3. The "problem" with the F3 is that I don't need the meter and would prefer a mechanical shutter but for this camera, I might make an exception. From my distant memory I think that the F3 felt more refined but I haven't handled one in a long time and have never owned the two at the same time (I usually own one SLR at a time).
