ABSTRACT:
A lock pin is inserted into a hole of a lens holding frame in order to lock a blur correction lens when blur correction is not executed. An optical axis of the blur correction lens and an optical axis of a photographic optical system match when the blur correction lens and the lens holding frame have fallen in the gravitational direction by their own weight and the lock pin and the hole have come into contact with each other.
