10 and 12 researched events on one shared scale. Fujifilm 1934–present, Topcon 1932–present.
The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
Fuji Photo Film Co., Ltd. was established in January 1934 after the photographic-film operations of Dainippon Celluloid were separated under a government industrial plan. The Ashigara factory began film, photographic paper, and dry-plate production. An Odawara site was added in 1938 as the company widened its materials and chemical base.
The Odawara works began optical-glass production in March 1940 and lens production the following month. More than a dozen glass types were made by the end of that year. The first company-built camera was a military aerial-observation camera, not a civilian Fujica. In 1944 Fuji acquired Enomoto Kogaku Seiki and formed Fuji Photo Optical, creating a separate precision-optical company within the group.

The Fujica Six IA appeared in April 1948 as the first commercial Fujica still camera. Initial bodies and shutters were supplied externally, and production delays exposed the difference between group capability and complete vertical integration. Camera manufacture was consolidated at Fuji Photo Optical in 1950. Odawara developed new high-index and rare-earth optical glasses and produced Crystar, Fujinar, and other lenses; the 1954 Leica-thread Fujinon 50mm f/1.2 is an early documented use of the Fujinon name. In 1957 Odawara's lens-production equipment and technology, with some staff, moved to Fuji Photo Optical.

Fujica expanded through 35mm rangefinders and automatic-exposure cameras, including the 1962 Fujica 35 Auto M, the 1963 Fujica Half, and the 1967 Compact 35. Fuji also developed the Single-8 cartridge and camera system, introduced in 1965 after its earlier Rapid-8 approach was abandoned in response to Kodak's Super 8. The 1968 G690 began a professional 6×9 rangefinder branch. Fuji Photo Optical participated across the camera, lens, and motion-picture programs.

The Fujica ST701 of 1970 opened the company's M42 SLR family. The ST801 followed in 1972 with open-aperture metering, a 1/2000-second top speed, and EBC Fujinon lenses; the electronically controlled ST901 arrived in 1974. Fuji's Electron Beam Coating first reached a marketed lens on the Single-8 Z800 zoom in December 1971, then interchangeable ST801 lenses in September 1972, medium-format lenses in 1973, and large-format lenses from 1974. The fixed-lens GW690 of 1978 simplified the earlier interchangeable-lens G system.

Fujica shifted its 35mm SLRs from M42 to a proprietary bayonet in 1979. The export STX-1 and AX-1, AX-3, and AX-5 families used Fujica X-mount and EBC X-Fujinon or X-Fujinon lenses with different automatic-diaphragm and exposure capabilities. This mount has a 43.5mm register and no direct relationship to the digital Fujifilm X mount introduced decades later. Screw-mount SLR production ended during the transition, and the Fujica 35mm SLR branch ended in the mid-1980s.
Fuji introduced the one-time-use QuickSnap in 1986 as film with a lens, creating a mass-market camera category tied directly to film manufacture and processing. The GX680 also appeared in 1986 as a 6×8 studio system with a revolving back, view-camera-style movements, and a thirteen-lens GX range. In 1988 Fuji demonstrated the FUJIX DS-1P, a prototype camera designed to record digital image data to a memory card; a commercial electronic still-camera line followed rather than the prototype itself entering ordinary retail sale.

The 1998 TX-1 panoramic rangefinder, sold internationally as the Hasselblad XPan, switched between 24×36mm and 24×65mm frames on the same roll and used jointly developed Fujinon lenses. Fuji's professional digital and medium-format work also converged with Hasselblad in the GX645AF program. Contemporary corporate reporting described the GX645AF as jointly developed, with Fuji Photo Optical integrated into manufacture and marketing.

Fuji Photo Optical changed its name to Fujinon Corporation in October 2004 to unify corporate and brand identity. In 2006 the Fuji group adopted a holding-company structure: FUJIFILM Holdings became the parent and FUJIFILM Corporation the main operating company. Fujinon Corporation merged into Fujifilm Corporation in July 2010. A parallel manufacturing reorganization created Fujifilm Optics from Fujinon Mito and Fujinon Sano, preserving specialist production in the group under new legal names.

The fixed-lens X100 appeared in 2011 and the interchangeable-lens X-Pro1 in 2012, establishing the present Fujifilm X system and XF Fujinon lens line. The larger-format GFX system followed in 2017 with GF lenses. Fujifilm Optics continues camera, interchangeable-lens, broadcast, cinema, binocular, projector, and industrial-optics production. This living Fujinon identity is a continuation of group optical capability, but modern X and G mounts require their own catalog branches rather than being attached to old Fujica X or film-era serial assumptions.

Tokyo Kogaku Kikai Kabushikikaisha was established in September 1932 from K. Hattori's surveying-instrument operation and lens facilities acquired from Katsuma Kogaku Kikai. It began with surveying instruments, binoculars, cameras, and military optics, then moved its head office and main works to Itabashi in April 1933.
The 6×4.5cm Lord entered production in July 1937 as Tokyo Kogaku's first civilian camera, but wartime conditions limited it to roughly fifty examples. The folding Minion followed in 1938, while the wider works concentrated on surveying, binocular, aerial-camera, and military optical production until the factory closed briefly at the war's end.
Authorized to resume civilian work in November 1945, Tokyo Kogaku exported binoculars and restarted cameras from surviving Minion parts. The Minion 35 appeared in 1948, domestic camera sales resumed in limited form in 1949, and ophthalmic instruments began in 1947. This diversified reconstruction led directly to the Topcon 35 in 1953.
Primoflex twin-lens reflex cameras, the Topcon 35 rangefinder family, and Topcor lenses turned photography into Tokyo Kogaku's leading postwar business. The 1957 Topcon R opened a professional 35mm SLR line, while the company-designed Topcon Horseman 960 of 1959 began a long-running large-format branch that outlasted the small cameras.

After becoming an affiliate of Tokyo Shibaura Electric in 1960, Tokyo Kogaku widened its camera program. The Topcon PR was Japan's first domestic lens-shutter 35mm SLR, and the 1962 Topcon RS answered a development request from American distributor Beseler. These cameras prepared the separate leaf-shutter and UV-mount branch.

The Topcon RE Super brought built-in TTL full-aperture metering to a production 35mm SLR in 1963. Slits in the reflex mirror fed a cell behind it, while the RE Auto-Topcor lens relayed aperture information to the body. The 1964 Topcon Uni extended mirror-meter thinking to an interchangeable-lens, lens-shutter SLR.

Tokyo Kogaku developed two distinct SLR paths: the professional RE family with RE Auto-Topcor lenses on its Exakta-derived bayonet, and the lens-shutter UV family that culminated in the Unirex. Beseler names on American-market bodies and later outside-made RE and K-mount products make engraving, interface, and maker attribution separate questions.

A Fukushima production company was formed in 1969, followed by service and sales subsidiaries in Europe and the United States in 1970 and Singapore in 1979. As ophthalmic and electronic surveying instruments reshaped the business, Topcon ended sales of 35mm cameras in December 1980; Horseman large-format production continued.
Successful electronic distance meters and the RM-100 refractometer accelerated Tokyo Kogaku's transition into an optomechatronics company. The first overseas production base opened in Hong Kong in 1986. In April 1989 the business adopted Topcon Corporation as its legal name, elevating the familiar camera trademark to corporate identity.
Topcon transferred Horseman camera manufacturing operations in March 1992, completing its withdrawal from cameras. The continuing company expanded instead through machine-control and precision-GPS acquisitions, introduced combined retinal and tomographic imaging, and made Sokkia a subsidiary, carrying precision optics into positioning and eye care.
Topcon concentrated resources on positioning, eye care, and agricultural automation, combining optical instruments with software, connectivity, and machine control. Fully automatic OCT imaging, construction guidance, GNSS, and digital agriculture show how the same precision-measurement tradition continued after consumer cameras had left the product range.
A management buyout backed by KKR and JIC Capital took Topcon private, and its shares were delisted on December 2, 2025. Current management remained in place while the company pursued longer-term investment in healthcare, agriculture, and infrastructure. The operating manufacturer continues from its historic Itabashi base.
