The XR-S is an SLR for 35mm film introduced c. 1981. It is based on the XR7 model from Ricoh, but with the addition of solar cells mounted on the sides of the pentaprism housing. In brighter light conditions, the solar cells would recharge a special rechargeable "Battery S" which powered the metering circuit. Ricoh claimed that battery life exceeding 5 years was possible with this system[1]. Failing this, a pair of standard 1.5-volt SR44/LR44 cells could be substituted, but the solar cells were disabled in this case.
