is a brand of optical lenses made by Fuji Photo Film Co., Ltd, now known as Fujifilm. Fujifilm's Fujinon lenses have been used by professional photographers and broadcast stations as well as in cinematography. Originally established as a photographic material manufacturer, Fujifilm aimed to become a comprehensive photographic enterprise. In March 1940, the company began manufacturing optical glass at its factory in Odawara, Japan, which marked the start of the Fujinon brand. Although the initial goal was to produce lenses and cameras for consumer use, the outbreak of World War II forced the company to shift its focus entirely to military optical equipment. In April 1940, Fujifilm completed its first camera, an aerial camera for the Japanese Navy.
To meet the rapidly growing military demand, Fujifilm expanded its production capabilities by acquiring existing optical manufacturers. In March 1944, the company acquired (established in 1934), which primarily manufactured binoculars, and renamed it . While post-war conditions led to the dissolution or sale of several other acquired companies and facilities, Fuji Photo Optical survived. They were proud of their use of expensive platinum crucibles to get the purest glass achievable at the time. In 2004, Fuji Photo Optical Co., Ltd. changed its name to , adopting its brand name, before being integrated into Fujifilm in 2010.
Fujifilm also pioneered Electron Beam Coating (EBC) which, according to Fujifilm, represented a new high in lens precision and performance. The EBC process was significantly different from other coating processes in the number of coatings, the thinness of the coating, and the materials used. Fujifilm claimed they were able to apply as many as 14 layers of coating and used materials such as zirconium oxide and cerium fluoride, which could not be used in conventional coating processes.[1] The first lens to offer Electron Beam Coating was the EBC Fujinon 55mm F3.5 Macro in 1972. Light transmission for the coating was said to be 99.8%. EBC later evolved into Super-EBC and HT-EBC (High Transmittance-Electron Beam Coating).

M42 system cameras
Fuji Photo Film manufactured and sold nine distinct 135 film camera models with the M42 lens mount between 1970 and 1978, including cameras aimed at the entry-level user (ST-601, 605), enthusiast (ST-701, 801), and professional (ST-901, AZ-1) markets.Fujinon M42 screw mount

Fujica X cameras
The Fujica AX-1, launched in 197x, introduced the Fujica X bayonet mount to replace the previous line of M42-mount SLRs. Many of the initial lenses for the Fujica X mount share optical designs with the late M42 Fujinon lenses.
TX-1 and TX-2 cameras
The Fujifilm TX-1 is a rangefinder which captures images in standard 24×36mm format or panoramic 24×65mm format on 135 film, introduced in 1998. Outside of Japan, it was marketed by Hasselblad as the XPan. It was succeeded by the TX-2 / XPan II in 2003.
The crop factor for the panoramic format (based on diagonal angle of view) compared to "full-frame" 135 is ; for example, the 90mm lens in panoramic mode would have the equivalent coverage across the diagonal of a lens with a focal length of approximately mm on a standard 135 film camera.
Fixed-lens cartridge cameras
Fuji Photo Film also made cameras compatible with a proprietary square format (Rapid) on 135 film in special cartridges, designed to compete with 126 film cameras such as the Kodak Instamatic, and 110 cartridge (Pocket) film cameras.

Large format lenses
Fujifilm sold large format lenses in the following series:
SWD (Super Wide Deluxe): ultra wide angle lens with an angle of view > 100° and maximum aperture of
SW (Super Wide): ultra wide angle lens with an angle of view of approximately 100° and maximum aperture of
W (Wide): wide-angle lens with an angle of view 70–80° and a maximum aperture generally with some exceptions
CM-W (Compact Wide): angle of view 70–80°, maximum aperture generally
A (Apochromat): normal lenses with an angle of view 50–70° and a maximum aperture of
C/CM (Compact): moderate wide-angle lens with an angle of view around 65°
BBL (Barrel): not mounted in shutter
L (Long focus): Tessar-type construction
T (Tele Type): telephoto lenses with an angle of view 25–35°
SF (Soft focus): deliberately undercorrected spherical aberration
Medium format lenses
G690
Fuji Photo Film introduced a new line of medium format (6×9) rangefinder cameras with interchangeable lenses in 1968 with the Fujica G690; in time, several other cameras were introduced, including two with 6×7 frame sizes.
Fixed lens cameras
The first fixed-lens medium format cameras were named Fujipet and took square (6×6) format pictures.After the G690/G670 line of interchangeable-lens rangefinders was discontinued, Fuji Photo Film produced a series of fixed lens cameras, most fitted with rangefinders, with nominal frame sizes of 6×4.5, 6×7, 6×9, and 6×17cm.
GX680
Fujinon GX (M) are lenses for the Fuji GX680 series of cameras, which take pictures with a 6×8cm (nominal) frame size.
GX617
The GX617 is an interchangeable-lens camera that takes panoramic photos with a nominal frame size of , which requires illuminating a circle with a diameter of , so GX617 lenses are comparable in size and optical construction to large format lenses. All GX617 lenses are fitted with a Copal No. 0 leaf shutter, with shutter speed settings ranging from 1 to sec plus (B)ulb.
GX645 AF
Hasselblad and Fujifilm jointly designed the H system cameras and lenses, with Fujifilm responsible for manufacturing. Each lens has an in-lens electronic leaf shutter, and the HC lenses also were sold with Fujinon branding. The Hasselblad H1 was sold with cosmetic changes as the Fujifilm GX645AF, but subsequent H system cameras do not have a Fujifilm equivalent. H system cameras accept backs which use either 120 film in the 645 format or several different sizes of digital image sensors, all of which are larger than the frame size of 135 film or equivalent "full-frame" sensors.
The 645 format is nominally 6×4.5cm, but actual frame measurements are , which gives a crop factor (aka focal length multiplier) of compared to 135 film. For comparison, a H system lens with a focal length of 80mm using an H system film back would have the equivalent coverage of a lens with a focal length of approximately mm on a "full-frame" camera.
