Abstract:
1. An optical apparatus comprising: an image shake correction optical element configured to be driven in a movable range including an optical origin position; a position detector configured to detect a position of the image shake correction optical element; a locking mechanism configured to mechanically limit movement of the image shake correction optical element within a lock range which includes the optical origin position and is narrower than the movable range; a memory configured to store 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; and a controller configured to control a position of the image shake correction optical element based on a control origin position, the control origin position being one of a first origin position obtained from the first reference position and the first distance, and a second origin position obtained from the second reference position and the second distance, wherein the controller performs correction of at least one of the first distance, the second distance and the control origin position based on at least one of a difference between a detection result of the position detector and the second distance when moving the image shake correction optical element from the first origin position to the second reference position, and a difference between a detection result of the position detector and the first distance when moving the image shake correction optical element from the second origin position to the first reference position.
