Minolta (ミノルタ, minoruta) was a Japanese company that, under one name or another, manufactured cameras from 1929 to 2003. It produced cameras for many film formats, from 16mm film to medium format. In the 1950s Chiyoda, as it was then called, ventured beyond production of cameras and binoculars into business services, especially photocopiers. Most branches of the company were related to optics: the copier branch, the exposure meter branch, etc. Minolta was succeeded by Konica Minolta after the merger with Konica in 2003.

The company was founded in Osaka on November 11, 1928 by Kazuo Tashima, under the name Nichidoku Shashinki Shōten (日独写真機商店, meaning Japan-German Camera Store). Tashima got support from the German camera technicians Billy Neumann and Willy Heilemann, and the first cameras used lenses and shutters imported from Germany. A plant was built in Mukogawa (武庫川), in the prefecture of Hyōgo (兵庫県). The first camera produced by the company was the Nifcarette released in 1929. It was followed by the Nifcaklapp and Nifcasport folding cameras and by the Nifca-Dox strut-folder, all taking film plates or pack film. At this early period, all the cameras were directly advertised and distributed by the company, which was using a round logo with the letters N, D, PH and Co assembled inside a circle, surely for Nichi Doku Photo Company. In 1930, a strike occurred in the Mukogawa plant, whose director was Willy Heilemann. Heilemann dismissed all the strikers and opposed Tashima, who was favouring more moderate measures.

In 1931 the company was transformed into a stock corporation named Molta Gōshi-gaisha (モルタ合資会社), where Molta is an abbreviation of the German "Mechanismus Optik und Linsen von Tashima" ("Mechanism, Optics and Lenses by Tashima"). The mention of Germany disappeared from the company name, and Heilemann and Neumann left the company respectively in November 1931 and in 1932, to found their own Neumann & Heilemann company, taking some employees with them. The camera range was accordingly renamed: the Nifcarette became the Sirius Bebe, the Nifcaklapp became the Sirius and the Nifcasport became the Arcadia. The cameras were still distributed by the company itself for a couple of years, and the Sirius and Arcadia were also distributed by Misuzu Shōkai as the Lomax and Eaton. Molta later entered an agreement with the Tokyo-based distributor Asanuma Shōkai, and the Sirius and Arcadia plate cameras were replaced by the Happy (whose brand name was owned by Asanuma). The Asanuma company would distribute the Happy and Minolta cameras and assume all the advertising until 1945.

The name Minolta was applied for and registered in 1933, and it was first used for a camera plainly called Minolta, inspired by the Plaubel Makina. A round MTS logo appeared at the same time, perhaps standing for "Molta Tashima" or "Minolta Tashima". Many sources say that the Minolta name was crafted from "Mechanismus, Instrumente, Optik und Linsen von Tashima" ("Mechanism, Instruments, Optics and Lenses by Tashima") but it is more likely a backronym, inspired by (i) minoru ta (稔る田), "ripening rice-fields" (a strong image of health and fruitfulness in Japan, and in Japanese pronounced identically to "Minolta"), and (ii) "Molta" itself. All the later model names included the word "Minolta", but the company name and brand name would differ until 1962.
In 1934, the company released the Minolta Vest, originally designed by Ehira Nobujirō, with an innovative system of collapsible boxes replacing the bellows. The Semi Minolta was announced at the very end of 1934 and sold from 1935. It was the second or third 4.5×6cm camera made in Japan. In 1936, the company created the subsidiary Nippon Kōgaku Kikai Kenkyūjo (日本光学機械研究所, meaning Japanese Opto-mechanical Research Institute) in the city of Amagasaki (尼崎市), in the Hyōgo prefecture, to manufacture the bakelite cameras such as the Minolta Vest, Minolta Six and Baby Minolta. This subsidiary was soon merged into the main company, and became the Amagasaki plant. In February 1937, the company opened a third plant in the city of Sakai (堺市), in the Osaka prefecture.
From 1937 to 1945
|Chiyoda Kogaku, the company name from 1937 to 1962.|
In September 1937, the company became Chiyoda Kōgaku Seikō K.K. (千代田光学精工㈱, meaning Chiyoda Optics and Precision Industry Co., Ltd.), abbreviated "Chiyoko" (千代光) on some logos and publications. (The word Chiyoda was created with the characters 千代, meaning "one thousand generations" and 田, the first character of Tashima's name; it conveys the meaning that Tashima's company will last a thousand generations.) The same year 1937, the company established closer ties with Asanuma Shōkai, which quit distributing other cameras to concentrate exclusively on cameras from the Chiyoda company. This association became so close that many customers believed that the Minolta cameras were made by Asanuma; the agreement lasted until the end of the war, but the two companies retained some commercial contacts for some time afterwards.
The two companies organized a show in December in the Tōkyō Kaikan (東京会館, a reception lounge in Tokyo, near the Imperial Palace) to celebrate the new agreement. Three expensive and advanced new models were displayed at this show: the Auto Semi Minolta was the first serial produced Japanese camera with a combined range and viewfinder, the Auto Press Minolta (an evolution of the Minolta and Auto Minolta Makina copy) was the first Japanese camera synchronized for flash and the Minoltaflex was the second Japanese 6×6 TLR. It seems that the taking lens of the Minoltaflex was made by the company, surely in the Sakai plant — these were perhaps the first lenses made by Chiyoda.
The production of Rokkor lenses began in 1940, but they were only for military use. It also produced military ordnance, including hand-held cameras for aerial reconnaissance. The civilian camera production was stopped around 1943. At about that time, the company apparently made one or more prototypes of an interchangeable-lens TLR camera, which was the first 6×6 TLR in the world to have interchangeable lenses.
The three original plants of Mukogawa, Amagasaki, Sakai ended up participating to the war effort. A fourth plant was opened in Komatsu (小松) in 1939, initially specialized in machine tools. In 1942, the Japanese Navy asked the company to open a glass melting facility; the new plant was built in Itami and only operational in 1944. In 1943, the company also took over Fujimoto's plant in the city of Nishinomiya (the former Neumann & Heilemann factory), which became Chiyoda's Nishinomiya (西宮) plant. It perhaps continued the production of Fujimoto leaf shutters for a short time.
Early postwar period
|-||Semi Minolta IIIB (Image rights)|
The company resumed camera production shortly after the war with the Semi Minolta III. This camera was equipped with a Rokkor 75/3.5 that was the first Japanese coated lens commercially available, and also the first lens made by the company for civilian use. The company also absorbed the optical section of the Toyokawa Navy Arsenal (Aichi prefecture), which became the Toyokawa (豊川) plant in November 1946.
In 1950, Chiyoda released the Konan-16 Automat, a subminiature camera that used its own 16mm film format. Throughout the 1950s, the range consisted of TLR cameras, 4.5×6 folders, 35mm viewfinder and rangefinder cameras and 16mm subminiature cameras.
|The SR-1 succeeded the SR-2.|
Introduction of the SLR
In 1958 Chiyoda produced its first planetarium projection apparatus and in the same year it introduced the SR-2, its first 35mm SLR camera and one of the first to combine several features of the modern SLR like pentaprism viewfinder, instant-return mirror, bayonet mount lenses, lever advance and auto-resetting frame counter. In 1959 Chiyoda started to produce photocomposing machines, copiers, and special projectors. Some of these products are still (2007) produced by its successor Konica Minolta. In 1962 the company name became Minolta Camera K.K. (ミノルタカメラ㈱, meaning Minolta Camera Co.), unified with the brand name. A significant camera launch of that year was the introduction of Minolta's first SLR with built-in CdS meter, the Minolta SR-7. That effort lead to the production of versatile and sensitive CdS-sensor-based light meters, a quite successful chapter in the company's history. Minolta's successor Konica Minolta is still making high precision light measuring instruments. In 1964 the company started that business with a CdS-meter for photography, the View Meter 9. In 1968 the company's meters were renowned so that American Astronauts used the special Minolta Space Meter as measuring accessory for the cameras they used in the Apollo spaceships and on the Moon. Further light and colour meters were developed later. The Auto-Meter color measuring instruments and the Flash Meter series were renowned among photography professionals. The Minolta SR-T series of SLR cameras introduced in 1966 was a big success and the Minolta SR-T 101 was the world's best selling camera of its type in its time.source needed
Cooperation with Leitz
|XD-7 with two AE modes.|
Minolta signed a cooperation agreement with Leitz in June 1972. The first products resulting from this appeared in 1974: the Minolta XE SLR and the Leica CL rangefinder camera (sold in Japan as the Leitz Minolta CL). The XE was the basis for the 1977 Leica R3. The final result of the association with Leitz was the Minolta XD-11 (the same as XD-7, and the basis of the Leica R4). It was the first 35mm SLR camera combining both aperture priority and shutter priority automatic exposure modes. Many Rokkor lenses of the new MD series, usable in both automatic modes, were produced for this exciting camera.
In 1981, Minolta launched the CLE, a rangefinder camera with M-mount, the first one to have (aperture-priority) automatic exposure. The metering system was of the "TTL OTF" type (through the lens, reflected off the film), first introduced by Olympus in 1975 on the OM-2 SLR camera. The CLE was also the first Minolta camera to have TTL flash automation, together with the X-700 SLR introduced the same year. The X-700 did much to keep and stimulate interest in photography world-wide, with a 'faster speed' program that made best use of new, better quality, faster films. It built on the advanced exposure system of the XD series, with a chassis based on the XG-M that was strong enough to take a motor drive. It also had AE lock, a much improved exposure-adjustment dial and TTL flash was supported by a 1/60s maximum flash synch via a silk horizontal-travel shutter to maximise ambient light when hand-held. It had a complete MPS range of professional accessories. This model won the first European Camera of the Year award in 1981, and sold over 3 million copies over nearly twenty years.
In 1982 the company's founder Kazuo Tashima stepped down as president of the company, and his son Hideo Tashima became his successor. Kazuo Tashima stayed in the company as chairman of the board until his death in 1985, at the age of 85.
The Nishinomiya plant, which hosted research and development activities as well as a service center, was closed in April 1985.
The Minolta 7000 AF SLR camera was introduced in 1985. It was the world's first "in-body" autofocus SLR. Before this time manufacturers had dabbled with lenses that focused themselves but that fitted their existing, manual-focus SLR cameras. Unlike other manufacturers, Minolta invested much of its resources in the new autofocus cameras, at the expense of its manual focus SLRs, which were repositioned as amateur level cameras. It was the first manufacturer to put the mechanism and electronics for the autofocus system into its SLR camera bodies and so the modern SLR was born. The rest of the camera had an advanced design, with liquid crystal screen display, built-in film winder, and a body built largely of plastics.
For five years beginning in 1985, Minolta was the biggest seller of SLR cameras in the worldsource needed, because of the 7000 and the later Alpha/Dynax/Maxxum system. However Minolta did not hang on to its technological lead for long as Canon and Nikon both introduced new autofocus designs of their own, with a wide array of new lenses and professional bodies. Minolta in turn tended to concentrate on the affordable end of the SLR market, and sought revolutionary rather than evolutionary changes. Among camera aficionados, Minolta was known both for its very high performance-to-price ratio and its constantly changing array of new models.
After popularizing the plastic-bodied, push-button-controlled SLR with the 7000, and a relatively unsuccessful line of complex 35mm SLRs with a electronic 'expansion card' feature, the company moved towards a more traditional user interface in the mid-90s with the 600si Classic. This interface was carried forward into its popular pro-level Minolta Alpha/Dynax/Maxxum 9 and later, the Maxxum 7. Unfortunately for Minolta, its autofocus design was found to infringe on the patents of Honeywell, a U.S. corporation. After protracted litigation, Minolta in 1991 was ordered to pay Honeywell damages, penalties, trial costs and other expenses in a final amount of 127.6 million dollars.
Like other camera manufacturers, Minolta faced difficulties in building low-priced, consumer level cameras, though its emphasis on this sector of the market may have affected the company more than some other brands. The company was one of the first to offshore production of its cameras from Japan to Malaysia, China, and other countries offering less expensive labor costs. Minolta occasionally redesigned parts in existing models with less expensive materials, or introduced new, less expensive designs, all in an effort to cut costs. In 1996 Minolta became engaged in the attempt to establish a small versatile modern user-friendly film cartidge type to replace 35mm film. Like some other camera and film makers it launched several fully automatic cameras for the new Advanced Photo System, added APS film adapters to its film scanners and even created its new autofocus SLR camera system for APS film, with the new Minolta V mount.
The company began offering consumer-level digital cameras in the late 1990s. With the DiMage X, Minolta solved the problem of the protruding optical zoom lens on pocket digicams. Its folded lens design allows an optical zoom lens to be totally contained within the body of the camera. This makes the cameras that use this design truly pocketable, faster to turn on and better protected from knocks and damage.
Minolta released two too expensive but innovative DSLRs for commercial markets (not professional photographers) before other makers:
- 1995 Minolta Alpha/Dynax/Maxxum RD-175 / Agfa ActionCam (Minolta AF mount)
- 1999 Minolta Vectis RD-3000 (Minolta V mount)
|Konica Minolta DSLR.|
They did not sell too well and did not lead nor define the market for digital SLRs, but have maintained a cult status among some Minolta collectors.
As a result, Minolta has been criticized for its slowness to bring out modern, competitive digital SLR cameras for the popular SLR photography market, compatible with the many popular Alpha/Dynax/Maxxum-mount lenses in use. In late November 2004, the new Konica Minolta company finally released the much anticipated Konica Minolta Alpha/Dynax/Maxxum 7D Digital SLR and the innovation continued. What sets the 7D DSLR apart from the competition is the built-in image stabilization which works with any electronic autofocus lens attached to the camera body.
Konica Minolta: too little, too late...
In October 2003 Minolta merged with Konica to form Konica Minolta. All new cameras after that time were badged as Konica Minolta, although, with reference to camera designs, Minolta remained the dominant partner.
As of spring 2006, Konica Minolta has withdrawn from the camera business entirely. The digital camera manufacturing assets have been acquired by Sony, but film camera production is ceasing, and the film and mini-lab divisions are set to close within a year.
Konica Minolta now is solely a business servicer with no photo division.

The Minolta Alpha/Dynax/Maxxum (Alpha in Japan and China, Maxxum in the Americas, Dynax in Europe, Africa and Asia) is a line of 35mm film SLR cameras built from 1985 to 2000 - some "new old stock" may still be available. The lenses and flash accessories for these are not compatible with the previous Minolta SR, SR T, and X-series of manual focus 35mm film SLR cameras, lenses and flashes. The last models appeared badged as "Minolta" despite of the merger with Konica in 2003.
Many of these models are alternatively labeled Alpha, Dynax or Maxxum and only a few model numbers are location-specific where an equivalent model number in another area of distribution uses another model number:
