ABSTRACT:
A camera exposure factor setting member, such as a diaphragm setting member, is movable in the vicinity of a fixed member, such as the lens barrel of an exchangeable lens. Either the fixed member or the exposure factor setting member is provided with a recess and the other one of them is provided with a lock member movable between a first position for permitting movement of the exposure factor setting member and a second position wherein the lock member engages a recess for preventing movement of the exposure factor setting member. The lock member is positively maintained at the first and second positions to prevent inadvertent movement therefrom.
