After losing my 8008 and 6006, a friend of mine was kind enough to lend me his F4 (he never uses it, preferring the N90). Here is what I found after a few days in the woods:
[Now that I've switched to Canon EOS bodies with their top and back controls wheels, the F4's ergonomics seem even more primitive.]
Conclusion: if you don't have a very specialized requirement, Nikon's lower line cameras, e.g., N90, 8008, are much better user machines.
