Abstract
A lens apparatus including an optical element includes a motor configured to drive the optical element; a position detector configured to detect a relative position of the optical element; and a controller configured to detect an origin of the optical element by returning the optical element to the origin by controlling the motor. The controller controls the motor so that a speed of the optical element moving to the origin is higher than a speed of the optical element moved by an operation of an operator.
