Abstract:
1. A lens apparatus attachable to a camera body, the lens apparatus comprising: 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 of the image stabilizing unit in the direction perpendicular to the optical axis; a gravitational direction determination unit configured to determine a gravitational direction based on an output from the position detection unit; a focal length detection unit configured to detect a focal length of the photographic optical system; 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, wherein the setting unit sets the holding position at which the image stabilizing unit is held based on the information concerning the gravitational direction output from the gravitational direction determination unit and information concerning the focal length output from the focal length detection unit; and a control unit configured to control the actuator based on information concerning a holding position to move the image stabilizing optical unit to the holding position.
