Abstract
A camera has a rangefinder device having an optical system constituted by a plurality of optical elements and a diopter adjustment mechanism capable of adjusting the observation diopter of the rangefinder device by operation by the user from outside the camera. In addition, there are provided an operating member that operates the diopter adjustment mechanism and an adjustment mechanism that effects adjustment such that the observation diopter of the rangefinder device is at a predetermined value when the operating member is in a prescribed position. By this means, a camera having a diopter adjustment mechanism whereby the relative positional relationship of the operating member and driven member can always be ensured such that the observation diopter gets equal to the predetermined observation diopter that is to be set when the operating member is arranged in the prescribed position. This can be realized by a straightforward construction.
