ABSTRACT:
An optical apparatus includes a photographic optical system including an image stabilizing unit supported by a support member via a plurality of elastic members, an actuator configured to drive the image stabilizing unit in a direction perpendicular to an optical axis thereof, a position detection unit configured to detect a position in the direction perpendicular to the optical axis of the image stabilizing unit, a gravitational direction determination unit configured to determine a gravitational direction based on an output from the position detection unit, a setting unit configured to set a holding position at which the image stabilizing unit is held based on information concerning the gravitational direction output from the gravitational direction determination unit, and a control unit configured to control the actuator based on information concerning the holding position to move the image stabilizing unit to the holding position.
