10 and 12 researched events on one shared scale. Fujifilm 1934–present, Miranda 1947–1989.
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.

Orion Seiki Sangyo began in 1947 and entered the 35 mm SLR field with the Orion T in 1955. The early name change from Orion Camera to Miranda Camera records a developing company identity, not an unrelated badge; the first production cameras established the mechanical platform that later carried the Miranda name.

The Orion T and early Miranda T series established the outer Miranda bayonet alongside an inner 44 mm threaded mount. The paired interfaces accommodated automatic-diaphragm and preset lenses, accessories, and adapters. This physical arrangement remained the defining compatibility boundary of the original Japanese Miranda SLR system.

A, B, C, D, and DR models brought lever winding, evolving mirror and screen arrangements, and a broader market range. Their differences are more than decorative in some cases, but the surviving model record is strongest at family level; individual production revisions need manual and specimen confirmation before further splitting.

Automex bodies combined automatic diaphragm operation with an external arm that communicated the selected aperture for metering. Selenium-meter Automex I and II models were followed by the CdS-equipped Automex III, creating an upper technical line whose MEX-REX lenses must be identified by their coupling hardware as well as focal length.
Miranda sold the F, FM, G, GT, Fv, and FvT alongside the Automex line. The G manual shows the intended system clearly: automatic bayonet lenses, preset lenses on the inner thread, and adapters on either interface. Its interchangeable screens and large mirror made the G a particularly flexible expression of the design.

Allied Impex's ownership connected the Miranda and Soligor distribution stories, and many Miranda-marked optics were sourced through Soligor. The relationship helps explain repeated lens families and badges, but it does not prove a single optical factory. Supplier attribution remains a specimen-and-document question for each lens generation.
Sensorex brought CdS through-the-lens metering behind the mirror while retaining finder continuity with Automex bodies. Sensorex C and Sensorex II refined the line. Mechanical bayonet fit continued, but metering behavior depended on lens-generation coupling, making a camera-and-lens pair more informative than either engraved name alone.

Sensomat, Sensomat RE, RS, and RE-II bodies offered a parallel stop-down-TTL or nonmetered route through Miranda's late period. This was not a simple replacement for Sensorex: it was an overlapping platform with its own meter operation and, in the RE-II, compatibility with later EC-lens full-aperture metering.

The Sensorex EE introduced a new internal aperture-information method for E lenses, and the EC series made the late lineup more compact. E and EC lenses can mechanically work across much of the system, but their full metering communication is generation-specific. The change marks a late, serious effort to modernize Miranda automation.
Miranda added the fixed-lens Sensoret, M42-mount TM variants, the electronic dx-3, and scientific Laborec bodies as the original SLR line approached its end. These branches require separate system boundaries: the TM's M42 interface and Laborec's specialist fittings are not interchangeable with the core Miranda bayonet system.

The EE-2 and dx-3 sit at the end of original Miranda camera production. Secondary histories place the manufacturing stop at the end of 1976 while stock continued through distribution afterward. The evidence supports an end-of-manufacture distinction; it does not make every later sale or repair a new factory-production event.
In the 1980s the Miranda name appeared on products sold by the British retailer Dixons, commonly associated with Cosina manufacture and Pentax K mounts. This is a trademark and distribution afterlife, not continuity of the Japanese Miranda bayonet/M44 factory system. The changed mount is a practical identification safeguard.
