ABSTRACT:
Provided in the interior of a camera are an automatic focus adjusting mechanism which initiates a rearward motion from a position for focusing on an object at short distances to a position for focusing on an infinitely distant object when a distance adjusting member is released from the latching connection in the charged position against a bias force in response to actuation of a camera release, a protection cover arranged to shutter the front of a photographic objective lens when not in use, and an electric motor for charging the distance adjusting member. When a control knob for the protection cover is actuated, as the energized motor charges the distance adjusting member, the protection cover is caused to open. When the control knob is de-actuated, the protection cover is closed by the action of the bias force, while simultaneously the distance adjusting member is released from the arrested connection so that the objective lens is retracted to a position equivalent to focusing on an infinitely distant object.
