Shōwa Kōgaku
Shōwa Kōgaku, later renamed Leotax Camera, was a Japanese camera maker.
It was founded in January 1938 by Nakagawa Kenzō (中川幹三) as Kyōei-sha (共栄社), based in Nippori (日暮里), Tokyo.[1] Nakagawa, a former engineer of Konishiroku, obtained financial support from Minagawa Shōten.[1] The company was renamed G.K. Shōwa Kōgaku (㈾昭和光学) at the end of 1938.[1] It became Shōwa Kōgaku Seiki K.K. (昭和光学精機㈱) at some time, certainly after the war, and was known under that name until 1956 or 1957,[2] when it was renamed Leotax Camera K.K. (レオタックスカメラ㈱).[3]
It made the Leotax rangefinder cameras until 1961, and it also made the Semi Leotax and Baby Leotax folders as well as the Gemflex subminiature TLR.
