ABSTRACT:
A camera includes a lens barrel which can be retracted into a camera body, and a lens barrel storage control apparatus. The lens barrel has a front lens group mounted in a front end portion thereof and a rear lens group movably disposed therein. The lens barrel storage control apparatus, first, controls a stepping motor for driving the rear lens group to locate the rear lens group at a standby position in the barrel, and then controls a DC motor for driving the lens barrel to retract the lens barrel into the camera body while keeping the rear lens group at the standby position. Also, when it is detected that the rear lens group is not located at the standby position, the control apparatus controls the DC motor to locate the lens barrel at a suitable position within a range where the lens barrel can be set in a photographable state.
