ABSTRACT:
An object distance measuring device in a camera, including an active object distance measuring mechanism for emitting measuring light toward an object to be photographed and receiving the measuring light as reflected by the object to detect the object distance is provided. A measuring zone is provided in a finder to indicate a measuring position at which the measurement of the object distance by the active object distance measuring mechanism is effected. A device is provided for varying the position of the measuring zone in the finder, and a device for varying the direction of the emission of the measuring light by the active object distance measuring mechanism in accordance with the varied position of the measuring zone is also provided.
