RICOH AD-1 with a 35mm F2.8 RIKENON lens, a black film camera with a date function. Model Name: AD-1 Lens: 35mm F2.8 RIKENON (rumored to be a copy of a Tessar, based on its construction and other features) Date function equipped (requires manual date and time setting, as this camera predates quartz date mechanisms.) This model is a full-frame version of the Ricoh Auto Half, allowing for large enlargements, and features a date mechanism. The exterior has minimal noticeable scratches. There is no severe haze or fungus in the lens. The light seals on the back cover need to be replaced. Includes a strap, lens cap, and LR44 batteries (new, for function check). The battery check lamp does not light up, but after opening the back cover and checking the AE, the aperture changes according to the brightness and shooting sensitivity. While I cannot say for certain, the AE mechanism seems to be working fine. Zone focus distance adjustment is also working without issue. The spring-wound film advance operates for about 10 shots in both single and continuous shooting modes when fully wound. The date imprinting function has not been confirmed. The self-timer function is normal. While replacing the light seals is essential for practical use, there appear to be no critical malfunctions at present. This product is a vintage, unserviced, used camera released in 1979, so the functionality of all mechanisms is unknown. We cannot guarantee permanent operation, so please consider it as-is.
