I never liked the F3, they just never felt or seemed right to me. Ditto for the F4 or F5. On the other hand I have several dozen F and F2's, and will eventually find a F6. My favorite non F series film Nikon SLR is the FM3A. I do know from my Nikon repair tech however, that the F3 proved considerably more reliable overall than the F4.
