(Redirected from Earth Kōgaku)
Earth Kōgaku K.K. (アース光学㈱) was a Japanese company based in Tokyo in the late 1930s and early 1940s. Before getting into camera production, the company was making a pocket monocular. In 1938, it released the Guzzi subminiature camera distributed by Sanwa Shōkai. It also made the Loren 3×4 folder from about 1940. On the cameras, the company name was displayed as EARTH KOHGAKU or EARTH K.K.
After 1945, the Guzzi was revived as the Top, ostensibly made by Top Camera Works; it is not known if this was the name of an actual company, maybe a successor to Earth, or a mere dummy name for Earth Kōgaku.
