Revision as of 19:41, 12 January 2007

Tōkyō Kōgaku, later Topcon, is a Japanese optical manufacturer, previously a manufacturer of photographic equipment.

History

The company was founded in 1932 as Tōkyō Kōgaku Kikai K.K. (東京光学機械㈱, usually translated as Tokyo Optical Company). The companies participating in its foundation were the measure instruments branch of Seikōsha and Katsuma Kōgaku Kikai Seisakusho (勝間光学機械製作所), both dependent companies of Hattori Tokei-ten.[1] As its name indicates, it was based in Tokyo.[2]

It was first an optical company, like Nippon Kōgaku (later Nikon). The company's first camera was the Lord, released in 1937, which was not a big success. It remained quite a minor camera maker until the end of the 1950s, even if its range of 6×6 TLRs met some success. It was also making 39mm screw lenses under the Simlar and later Topcor brands. The Topcon brand name appeared in 1953 on a 35mm camera. At about the same time the dependent company Yamagata Kikai was also manufacturing the Semi Oscon that was advertised together with the company's own cameras.

The company began the production of Topcon 35mm SLRs in 1957 (before either Nikon or Canon produced a SLR), and it very soon concentrated on these, stopping the production of all the other types. The Topcon RE Super, launched in 1963 at the Photokina, was the company's most innovative camera and one of its most rugged and versatile. It was the first SLR with a through-the-lens exposure meter. Pentax would follow the next year with the Spotmatic, and Nikon only in 1965 with the Nikkormat FT, and with the Photomic T prism for the Nikon F.

In parallel to the high end bodies, Tōkyō Kōgaku also manufactured simpler SLRs, at the beginning with a central shutter, later with a Copal Square focal-plane shutter.

The Topcon SLRs were imported in the USA by Beseler, which put its own name on the bodies. Some models were marked Hanimex when imported in the Commonwealth.

At the end of the 1960s, the company ceased to innovate on the SLRs, and produced variations on the same basic design until 1976. The bodies made after 1977 are not up to their predecessors, and the rumor says they were not designed by Tōkyō Kōgaku but elsewhere.

Tōkyō Kōgaku decided to stop the production of cameras in 1981. It thereafter concentrated on making specialist optical equipment of no direct relation to photography, and in 1989 took the name K.K. Topcon (㈱トプコン). It still (2007) exists.

Today the better Topcon models are eagerly collected in Japan. In 2003 Cosina designed and marketed an "Auto-Topcor" 58/1.4 lens (in Nikon F and M42 mounts) that externally resembles the genuine Tōkyō Kōgaku item and is even marked Tokyo Kogaku; it also created a variant of its M42-mount Bessaflex SLR whose distinctive pentaprism housing resembles that of the Topcon RE Super.
