1933-1936
Goro Yoshida, Saburo Uchida, and Takeo Maeda established the Precision Optical Instruments Laboratory in Tokyo in November 1933 to develop a high-grade 35mm camera. The Kwanon was a prototype, not a regular commercial line. The Hansa Canon reached the market in February 1936 under a joint arrangement: Nippon Kogaku supplied the Nikkor lens, mount, viewfinder optics, and rangefinder mechanism, while Canon's predecessor made the body and shutter and assembled the camera.
