12 and 12 researched events on one shared scale. Horseman 1933–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.
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.
Komamura Brothers began business in Kyoto, establishing the enterprise from which the later Komamura photographic company emerged. The date marks the commercial origin, not yet the formal postwar company or the Horseman camera brand, so those later milestones remain separate in the chronology.

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.
Komamura identifies 1947 as the establishment of the postwar company and the beginning of film-development operations in northern Japan. This legal and operational milestone followed the 1933 business origin and immediately preceded the company's first documented police-camera project.

The wooden PC-101 identification camera was developed for the National Police Agency in 1948. In 1950 Komamura announced the Horseman 102 for police identification work, giving the Horseman name a practical foundation in controlled, repeatable evidentiary photography.

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.

Komamura completed the Horseman 104 as an identification camera for the police. The model linked the early public-service cameras to the compact professional system that soon appeared under Topcon Horseman branding, combining Komamura direction with Tokyo Kogaku participation.

The 960, 760, 970, 980, and 985 developed the compact 6x9 press and technical-camera idea through several generations. Official service records preserve these distinct names alongside Super Topcor optics, while surviving manuals and systems show the importance of backs, cams, and rangefinder coupling.

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.
The VH and rangefinder-equipped VH-R carried the compact roll-film technical-camera concept into a mature system. Movements, interchangeable backs, ground-glass focusing, and model-specific rangefinder provisions made the cameras unusually versatile, but also created compatibility boundaries collectors must respect.

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.
Horseman 45FA, 45HD, and Woodman 45 brought folding-field portability to 4x5 photography. The 45FA and 45HD shared an 80 mm board concept but differed in rear movements, extension, focusing equipment, and front-rise control, so they represent distinct working bodies rather than trim variations.

The LS, LE, LX, and LX-C optical-bench cameras extended Horseman into modular studio work, with documented 4x5, 5x7, and 8x10 configurations. Their rail, bellows, standards, and interchangeable rear frames made format and movement capacity central parts of the system design.

SW612 and SW617 cameras turned 6x12 and 6x17 roll-film panoramas into purpose-built professional systems. Later Professional, SWP, SW612D, and SWD-II Pro variants brought interchangeable mounts, digital backs, and shift movements into the same wide-angle design tradition.

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.
DigiWide, DigiFlex, LD, VCC Pro, ISS-G3, TS-Pro, and Axella products translated view-camera geometry into digital workflows. Rather than treating a sensor as a fixed endpoint, Horseman used interchangeable mounts, bellows, rails, and standards to keep perspective and focus control available.

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.
Komamura transferred its photographic and broadcasting-equipment operations to Kenko Professional Imaging. Komamura continued separately in advanced imaging, while Kenko became steward of Horseman products, documentation, service information, and the professional-camera heritage.

Kenko Professional Imaging opened the Horseman Museum in Nakano in 2016 with cameras and accessories representing the brand's history, alongside then-current Axella and VCC Pro equipment. Current documentation preserves the system even though many historical bodies and lenses are no longer repairable.

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.
