The Nikon F Photomic FTN was introduced in 1968 (discontinued in 1974). The Nikon F Photomic FTN introduced the semiautomatic maximum aperture indexing and shutter speeds displayed in the viewfinder. The maximum aperture scale is visible on the face of the finder just above the lens. This is the only F Photomic finder with the shutter speed displayed in the viewfinder.
