詳細説明

The “Nikon F,” which combined Nikon’s optical and precision technologies, was a great success both at home and abroad, and was produced for 15 years until 1973, firmly establishing the Nikon and Nikkor brands.

The newly developed mirror box, pentaprism, bayonet, and other major parts were the same as those of the SP. However, the development of the mirror box and pentaprism mechanism had to overcome important technical barriers, such as the need for the mirror and lens aperture to automatically return to the open state instantly after shooting.

The bayonet mount was made of stainless steel to withstand the weight of the telephoto lens. In anticipation of the future, a 44 mm (34 mm for the Nikon S) inner diameter was adopted to allow the use of lenses with a large aperture ratio. This is the “Nikon F mount,” which has been used in the latest digital SLR cameras for more than half a century. This is the world’s longest originally designed lens mount for 35mm format SLR cameras.

The “Nikon F” maximized the characteristics of the single-lens reflex camera, which allows the photographer to view the image actually captured on the film in the viewfinder, and the viewfinder’s field of view was set to 100%. The shutter curtain is made of titanium material (0.02 mm thick). In addition to the shutter speed, the aperture is fully interlocked with the Nikon meter. (From Nikon website)
