PURPOSE:To effectively utilize a limited power supply voltage by shifting the timing of current supply peaks to respective motors for driving a mirror and a diaphragm. CONSTITUTION:In a camera system for supplying electric power from a camera to a lens through contacts 23a, 23b between them and driving the diaphragm of a lens by a motor 24, the diaphragm is driven to its stopping direction by driving a diaphragm driving motor 24 after a prescribed time from the start of mirror rising based upon the action of a mirror driving motor 12 and the diaphragm is driven in the opening direction after a prescribed time from the end of mirror down operation. Thus, the limited power supply voltage can be effectively utilized and the generation of malfunction can be prevented by a simple modification shifting the timing of the current supply peaks to respective motors.
