10 and 12 researched events on one shared scale. Fujifilm 1934–present, Yashica 1949–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.

Yoshimasa Ushiyama's Lake Suwa workshop began with electric-clock components, then entered camera manufacture through the Pigeonflex and early Yashimaflex/Yashicaflex twin-lens reflexes. The move joined precision mechanics to a fast-growing Japanese export industry and created the product name that soon became the company name.
Yashicaflex, Yashica A, C, D, LM, 635, Mat and related models built a broad medium-format range. The cameras evolved through crank winding, meters, 127 and 120/220 formats, and changing Yashimar, Yashikor, Lumaxar and Yashinon lens packages while retaining the familiar waist-level reflex form.
A United States sales organization, movie cameras and the first Yashica 35 rangefinder widened the business beyond TLRs. In September 1958 the legal maker became Yashica Co., Ltd.; period cameras show the change from Yashima to Yashica markings more reliably than the simplified chronology in later promotional literature.

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.

Yashica acquired Nicca's 35mm rangefinder operation, marketed the YE and YF, and absorbed the subsidiary over a longer interval than many summaries imply. Nicca experience contributed to Yashica's move toward interchangeable-lens cameras, although sources differ on the acquisition month and final legal absorption date.

The Pentamatic introduced Yashica's proprietary-bayonet 35mm SLR system, but its short production life was followed by the Penta J and J series using the widely shared M42 screw mount. Yashinon lenses could now travel across makers' bodies, and Yashica gained a more practical platform for its growing SLR range.

The Electro 35 family turned electronic shutter timing and aperture-priority exposure into a simple rangefinder experience. Successive G, GS, GT, GSN, GTN, CC and MC versions made the concept one of Yashica's defining products, even though the often-quoted lifetime production total is not supported by a surviving factory ledger.
Tomioka Optical, already a Yashica lens supplier, came under Yashica capital in 1968. It produced SLR and other lenses, joined Kyocera with Yashica in 1983 and became Kyocera Optec in 1991, preserving an optical-manufacturing line that outlasted Yashica-branded camera production.

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.

Yashica's cooperation with Carl Zeiss produced the Contax RTS and the shared Contax/Yashica bayonet. Zeiss supplied premium optical designs, while Yashica offered FX and FR bodies plus Yashica-branded DSB and ML lenses, creating an interoperable 35mm system without collapsing the partners' distinct design attributions.

The FX-1, FX-2, FR, FR I and FR II developed the consumer side of the shared mount, while the mechanically governed FX-3 became a long-lived entry body. Yashica ML lenses ranged from fisheye and fast normals to macro, mirror and zoom designs, sharing the bayonet and accessories with many Contax bodies.

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.
Yashica Co., Ltd. merged into Kyocera in October 1983. Yashica continued as a consumer camera brand beside premium Contax products, with overseas manufacturing, autofocus SLRs, compact cameras, Samurai half-frame models and specialist Dental-Eye bodies extending the catalog into the digital transition.

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.

Kyocera reported that intense digital-camera competition and inadequate cost reductions forced a major downsizing of its optical equipment group. Overseas sales companies closed, domestic camera operations contracted and the Yashica/Contax camera-making era ended, although Kyocera's optical-components business continued.

The Yashica badge entered a new Hong Kong-based trademark chapter and now appears on products promoted through a current YASHICA business. Separately, the Tomioka-derived Kyocera Optec operation continued industrial optical work and became Kyocera's Optical Components Division, so brand revival and manufacturing continuity are distinct stories.

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.
