ABSTRACT:
A camera including a camera body, a lens barrel, a power supply source to supply power to circuits of the camera, and a main switch to switch the power supply source between a power supplied status and power-not-supplied status. The lens barrel has a first position which is where the lens barrel is completely retracted within the camera body, a second position which is where the lens barrel is set when the main switch has gone into the power supplied status, and a reference position which is for positional control of the lens barrel with respect to the camera body. The reference position is between the first position and the second position of the lens barrel. If a new battery is inserted into the camera, the lens barrel is not moved, thereby preventing a camera holder from dropping the camera.
