11 and 10 researched events on one shared scale. Argus 1931–present, Fujifilm 1934–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.
International Radio Corporation built Kadette radios in molded cabinets in Ann Arbor. Charles Verschoor looked for a product that could keep the plant busy outside the radio season, and the company applied its plastics experience and mass-production ambitions to an inexpensive 35mm camera launched in May 1936.
The compact Model A paired a molded body and collapsible lens with a price far below imported miniature cameras. AF, B, A2B and A2F versions added focusing, a faster shutter-lens package, or exposure guidance, turning one successful idea into a family that helped normalize 35mm photography for American amateurs.
The C introduced rangefinder measurement, the C2 coupled it to the lens by an external gear, and the flash-synchronized C3 established the famous rectangular form. Its body-mounted shutter accepted a modest ecosystem of normal, wide and telephoto front assemblies from Argus and outside optical suppliers.

The K, 828-film M, A3, photoelectric-metered CC, postwar Model 19, A4 and C20 moved beyond the main A and C families. They tested half-frame options, built-in exposure aids, metal construction and streamlined forms, leaving a varied record of how Argus searched for the next durable amateur-camera formula.
Government work began before American entry into the war. In August 1942 Argus stopped civilian output, stored camera machinery and unfinished stock, and devoted the expanded Ann Arbor plant to military optical and radio equipment. The work broadened skills, employment and the factory complex before peacetime production returned.
Argoflex cameras carried Argus into 120 and 620 roll film, from the plastic E to Harley Earl-styled metal models and simplified Forty and Seventy-Five variants. The recalled Argoflex II, revised EM and EF, and later boxlike models show experimentation with film transport, flash and waist-level viewing.
The Model 21 brought a removable back, projected framelines, automatic shutter cocking and flash features. C4, C4R, C44 and C44R cameras developed that metal-bodied platform through coupled rangefinding, rapid advance and a proprietary interchangeable-lens system, distinct from the older C-series interface.

Sylvania reached an agreement to acquire Argus Cameras in 1956 and operated the business from 1957. The purchase placed the Ann Arbor maker inside a larger electronics company while its established cameras, projectors and optical products continued under the Argus name during a rapidly changing import market.

Standard and Match-Matic C3 editions refreshed the established camera, while C33 and Autronic models coupled exposure settings more closely to accessory meters or automatic controls. The changes made picture taking quicker but also reveal how Argus tried to update a body concept rooted in the late 1930s.
Mansfield Industries bought Argus in March 1962, and the combined concern adopted the Argus, Inc. name that May. Camera production moved away from Ann Arbor over the following years as the badge appeared on imported equipment, changing Argus from a predominantly local manufacturer into a broader photographic-products brand.
Domestic camera production had ended by 1969, though later imported and digital products reused the Argus name. The surviving Ann Arbor buildings, factory films, employee publications, collector surveys and the Argus Museum now preserve the manufacturing story and separate it from later trademark use.
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.
