Miyamoto Lens Kenkyūjo (宮本レンズ研究所) was a Japanese company based in Tokyo, Shinagawa in 1943.[1] It is listed in the April 1943 government inquiry as the maker of the Cyclon 3×4cm camera and its Cyclon 50/3.5 three-element lens.[2] The camera was distributed by Sankō-sha, the same company which sold rangefinder conversions for the Gelto and other cameras, under the same brand "Cyclon".
