ABSTRACT:
A camera is provided with an object distance measuring sensor for detecting an object distance, an object brightness measuring sensor for detecting an object brightness, a photographing lens, a position of which along an optical axis is variably set, and a diaphragm mechanism having an aperture value that is variably set. A single movable control member, that is moved in one direction upon a shutter release operation, a first cam for setting the position of the photographing lens in accordance with the movement of the control member, and a second cam for setting the aperture value of the diaphragm mechanism in accordance with the movement of the control member, are also provided. The camera also comprises a stop mechanism for stopping movement of the control member at an arbitrary position, and a control circuit for actuating the stop mechanism so that the control member stops in a position where the position of the photographing lens corresponds to the object distance detected by the object distance measuring sensor, and the aperture value of the diaphragm mechanism corresponds to the object brightness detected by the object brightness measuring sensor when the shutter release operation is executed.
