Abstract
A vibration reducing apparatus comprises a holding unit for holding a vibration reducing optical system, a vibration reducing drive unit for reducing vibrations of an object image by moving the holding unit, a lock unit for locking the holding unit in a predetermined position, a control unit for controlling the vibration reducing drive unit and the locking unit, and a determining unit for determining whether or not the holding unit should be locked in the predetermined position. The determining unit outputs a first predetermined signal to the control unit so as to lock the holding unit in the predetermined position at least once before operating the vibration reducing drive unit after switching ON an electricity supply. The control unit, upon receiving the first predetermined signal from the determining unit, controls the lock unit to lock the holding unit in the predetermined position.
