The Ricoh Auto Half (1962) is a distinctive half-frame 35mm camera with **spring-wound automatic film advance** — wind a side-mounted spring (like a vintage clock), and the camera advances film between exposures automatically. Selenium-coupled programmed exposure, fixed-focus 25/2.8 three-element Ricoh lens, leaf shutter. Tiny — 85 × 65 × 40 mm — much smaller than most half-frames. Iconic design with the spring winding key on the front, often decorated with cosmetic engravings.

Released 1962. Variants: Auto Half E (1966, refined cosmetic), Auto Half S (1968, slightly faster shutter). Production ran 8 years until 1970. The line was popular in Japan and exported to limited Western markets.
The Auto Half is a unique design — the spring-wound advance is unusual for any 35mm camera and means you can fire 36 half-frame exposures in rapid succession without manual winding. The body is also exceptionally small for a 35mm half-frame, fitting in a shirt pocket comfortably.
For 2026 buyers, the Auto Half is a cult collectible. Used at $60–180. The decorated cosmetic-engraved variants command premiums.
