Ricoh's half-frame 35mm compact — selenium auto exposure, spring-motor advance, 1962.
The Ricoh Auto Half is a fixed-lens half-frame 35mm camera from Ricoh, introduced in 1962. It exposes half-frame images, giving roughly twice as many exposures per roll of 35mm film. It became a long-running series known for its small size and spring-motor film advance.
This is a fixed-lens half-frame camera with a leaf shutter and a spring-wound motor that advances the film automatically after each shot. Exposure is handled by a selenium meter that needs no battery, driving automatic exposure. Focusing is fixed or scale-based rather than by rangefinder, and the spring motor removes the need for a manual advance lever between frames.
The Auto Half suits users who want a very small, easy-to-carry film camera for general, street and travel snapshots, with the economy of half-frame doubling the exposures per roll. The spring-motor advance and automatic exposure make it quick for casual point-and-shoot use.
When buying, confirm the selenium meter still responds to light, as these cells fade over time, and test that the spring-motor advance winds and releases correctly. Inspect the lens for haze and fungus, test the leaf shutter for sticking, and check the light seals. Verify the automatic exposure reacts to changing light and inspect the film chamber for cleanliness.
