The classic Nikon F helped establish Nikon as the leader in quality 35mm SLR photography back in late 50's, early 60's - and still holds up today! The Nikon F was Nikon's first SLR featuring interchangeable viewfinders and focusing screens. The Nikon F is fully manual with incredible toughness and reliability. This design was the first SLR to offer an optional battery-powered motor drive and optional perspective control 35mm lens.
