1926
ICA, Contessa-Nettel, Ernemann and Goerz merged under Carl Zeiss Foundation influence to form Zeiss Ikon AG with headquarters in Dresden.
Minolta and Zeiss Ikon
13 and 9 researched events on one shared scale. Minolta 1928–present, Zeiss Ikon 1926–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.
1920s
1927-1931
Early catalogs retained many predecessor-derived plate and roll-film families while the company developed clearer standardized lines including Box Tengor, Nettar and Ikonta.
Tashima opens Nishinomiya workshop
1928-1931
Kazuo Tashima founded Nichi-Doku Shashinki Shoten in 1928 to make cameras in Japan, opening a workshop in present-day Nishinomiya. With little local subcontract capacity and German technical guidance, the small firm made components in-house and released the Nifcalette in 1929, establishing the manufacturing culture behind Minolta.

The Contax 35mm rangefinder system, Super Ikonta folders, Ikoflex TLRs, Tenax, Contaflex TLR and Movikon cine cameras broadened the portfolio.

Minolta name reaches cameras
1933-1945
During the 1930s the young company adopted Minolta as a product and corporate identity while broadening camera production beyond its first folding models. Surviving public sources describe the period unevenly, especially wartime organization and factories, so the safe historical thread is the growth of a domestic camera and lens maker rather than a perfectly continuous model ledger.

1940s
1945-1959
Dresden works were dismantled, sequestered and nationalized, leading through VEB Zeiss Ikon toward VEB Kamera- und Kinowerke and Pentacon; the western legal seat and camera operation were rebuilt in Stuttgart.

Postwar cameras rebuild the line
1946-1958
Postwar production rebuilt around roll-film and 35mm cameras, including the Minoltaflex twin-lens reflex and Minolta-35 rangefinder families. By the late 1950s Minolta could turn camera-lens expertise toward instruments as well: its first planetarium appeared in 1958, the same year the SR-2 opened a long-lived 35mm SLR system.

Stuttgart revived roll-film folders and Ikoflex while introducing the Contessa 35 and revised Contax IIa/IIIa rangefinders.

1953-1966
The postwar Contaflex leaf-shutter SLR family evolved from fixed-lens bodies to Pantar and Pro-Tessar front-component systems with increasing automation.

SR bayonet anchors an SLR system
1958-1966
The SR-2 introduced Minolta’s manual-focus bayonet in 1958. Successive SR bodies and Auto Rokkor lenses turned it into a coherent system, while the 1966 SR-T 101 added full-aperture through-the-lens metering. Later MC and MD couplings extended body-lens communication without making every lens/body feature identical.

Contarex became the flagship 35mm SLR system, later joined by Special, Professional, Super and Electronic bodies and a wide Carl Zeiss lens range.

Hi-Matic photographs orbital flight
1961-1969
The fixed-lens Hi-Matic reached an audience far beyond ordinary advertising when John Glenn used one during Friendship 7 in 1962. Minolta also adapted an exposure meter for Apollo 8 and Apollo 11. These space-program episodes sat alongside overseas expansion and showed that the company’s precision optics, metering and compact-camera engineering could earn international trust.

Rokkor line broadens the system
1966-1977
The SR-T era supported a broad Rokkor range from everyday primes to fisheyes, macros, mirrors and early zooms. MC coupling let compatible bodies meter at full aperture; later MD signaling prepared bodies for more automated exposure. The 1967 catalog and later system guide show a maker selling a complete photographic system, not merely isolated cameras.

Leitz partnership crosses traditions
1971-1990s
Minolta and Leitz formed an unusually deep Japanese-German technical partnership. Their work encompassed the compact Leica CL, Minolta CLE, shutters, the XE/Leica R3 and XD/Leica R4 relationships, and lenses whose optical designs or complete assembly came from Minolta. The collaboration carried Minolta engineering into products wearing both companies’ names.

1972–present
Historic camera production ceased in 1972. The security branch continued and is now within ASSA ABLOY under IKON; Carl Zeiss later used Contax through Yashica/Kyocera and revived the ZEISS Ikon camera with a Japanese partner from 2004 to 2012.

Electronic SLRs refine manual focus
1973-1984
The professional XK/XM/X-1, XE, XD and X-series bodies made electronics central to Minolta’s manual-focus cameras. The XD combined multiple automatic exposure modes in a compact body related to the Leica R4, while the X-700 became the best-known late expression of the SR/MD system and kept manual-focus Rokkor lenses in wide use.

A-mount integrates autofocus
1985-1994
In 1985 the alpha-7000, Maxxum 7000 or Minolta 7000—its name varied by market—placed autofocus drive and control inside a production SLR body and launched the new A-mount system. The incompatible break from SR created a modern electronic platform whose cameras and lenses reached a broad public and shifted expectations for 35mm autofocus SLRs.

A-mount matures across markets
1985-2003
Minolta developed A-mount from the first 7000 and professional 9000 through xi experiments, enthusiast bodies and the Maxxum/Dynax 9 and 7. Its lens range expanded through macros, APO telephotos, G lenses, specialist optics and late D/SSM communication. Regional Maxxum, Dynax and alpha names describe one system lineage, not three mounts.

Konica and Minolta integrate
2003-2006
Konica and Minolta integrated management in 2003 and reorganized under the Konica Minolta name. The alpha-7 Digital/Maxxum 7D/Dynax 7D arrived in 2004 with body-integral CCD-shift anti-shake, carrying A-mount lenses into digital capture. It was a capable bridge, but the combined group soon chose to leave consumer camera production.

Camera assets pass to Sony
2006-2013
Konica Minolta withdrew from the camera business on March 31, 2006 and transferred selected digital-SLR assets to Sony. The agreement preserved compatibility for Maxxum/Dynax lenses and shifted service operations, while carefully stopping short of transferring the entire company. In 2013 the surviving group reorganized as Konica Minolta, Inc.

Optical work continues beyond cameras
2013–present
The Minolta camera line ended, but the corporate and technical lineage did not vanish. Konica Minolta describes optical design, glass-lens expertise and precision manufacturing as continuing core capabilities serving cinema projection, mobility, inspection and other enterprise fields. Its 2026 plan still names optical components within the company’s forward business program.
