Well... I cannot talk for or against the F3. I'm still using my old F (built in the Viet-Nam era) and it still fits the bill. One of the toughest body I ever had...

Otherwise, I do appreciate my newer Canon EOS 7N body. I must admit my sighting is less accurate than 30 years ago and electronics makes life a little easier when shooting fast subjects.

But my main body is my Nikon F, for its tank-like reliability.
