ABSTRACT:
An image blur prevention apparatus, includes a correction optical system for preventing an image blur a lock member for locking the correction optical system which sets the collection optical system immobile, and an operation portion which prevents optical system movement by operating the lock member. It prevents the correction optical system from rotational displacement due to its weight about a fulcrum at the contact position with the lock member, by always urging the correction optical system against the sliding surface in the direction of the rotational displacement. This is arranged by the foregoing structure to keep the state of the image blur prevention apparatus properly (so as to keep the optical axis of the correction optical system from inclining) during the period in which the operation of the correction optical system is regulated.
