"F" is for F: The Nikon F Photomic FTN
The Nikon F was Nippon Kogaku's first Nikon SLR camera. The Photomic FTN was a specific type of prism on the top of the camera.
Production of Nikon F cameras began in 1959. More than 780,000 Nikon F cameras were made. These take photos on standard 35mm film.
This camera had interchangeable lenses that remain compatible with Nikon's newest digital SLR cameras.
