An optical apparatus includes an image shake correction optical element driven in a movable range including an optical origin position, a detector detecting a position of the optical element, a locking mechanism limiting movement of the optical element within a lock range including the optical origin position and is narrower than the movable range. The apparatus further includes a memory storing a first distance between a first reference position in the movable range and the optical origin position and a second distance between a second reference position in the lock range and the optical origin position. A controller controls a position of the optical element based on a control origin position, and performs correction of at least one of the first distance, the second distance and the control origin position.
