ABSTRACT:
A motion compensation device, suitable for an optical system such as a camera, has a blurring motion compensation unit to compensate for blurring motion by driving an image blurring motion compensation optical system in a direction generally perpendicular to the optical axis. The device can lock the image blurring motion compensation optical system by a locking member even if there is no power supply. This is accomplished by using a magnet which attracts an iron piece mounted on a blurring motion compensation lens frame, and lock members which lock the blurring motion compensation lens frame. When an operation mode changeover switch changes over from the ON position to the OFF position, a contact unit of this operation mode changeover switch locks a coupling member of a lock ring. Accordingly, because the magnet attracts the iron piece even when there is no power supply, the blurring motion compensation lens frame can be locked by the lock ring.
