PROBLEM TO BE SOLVED: To surely execute an operation of releasing the locked state of a blurring correcting optical system and an operation of locking the system, and to prevent the operation from being stopped halfway. SOLUTION: The blurring correcting interchangeable lens 33 functions as an interchangeable lens provided with lenses 1 to 4, lenses 6 to 9, a shift lens 5, a shift lens frame 10, an X-axis VMC 13, a Y-axis VMC 14, a lock pin 11 and a lock solenoid 15. In the case of a pre blurring correction operation, a power is supplied to the X-axis VMC 13, the Y-axis VMC 14 and the lock solenoid 15, and then, a voltage transmitted from a power source 21 through a power supply terminal F:24 is monitored by a monitoring circuit 26, and in the case the voltage is equal to or below a prescribed value, the operation of releasing the locked state of the shift lens frame 10 is not executed by a drive control circuit 27. |
