The original Ricoh Auto Half was made in Japan by Ricoh from c.1960-1963[1], with revised versions appearing through the 1970s. Several styling variations are known. All were 35mm half frame cameras, with clockwork motor film advance for 25 to 30 exposures. The 25mm f2.8 3 groups 4 elements lens was surrounded by the selenium cell operating the exposure metering, setting aperture automatically, with manual override option. Shutter speeds were 1/30 sec.
