Abstract
At least one exemplary embodiment is directed to an optical apparatus which includes an acquisition unit adapted to acquire position information of a lens, and a control unit adapted to control a position of the lens by an amount of rotation of an operating member and the position of the lens. The control unit initializes a corresponding relationship between the amount of rotation of the operating member and the position of the lens when the position control of the lens is started.
