The F2 (especially the F2 titanium) is in my opinion the best 35mm SLR that Nikon ever made.

It has all the features I need (durability, reliability, mirror lock-up, interchangeable motor drives, interchangeable view screens, interchangeable viewfinders, 100% viewfinder accuracy, choice of four non-metered viewfinders, and battery independence).

I am still using one F2 that I bought new in 1971.
