Abstract
An image pickup lens includes a controller and a manipulator position detector configured to detect a position of a manipulator configured to accept a manipulation used to move the lens. When the manipulation of the manipulator becomes valid and a difference between the position of the manipulator when the manipulation of the manipulator is invalid and the position of the manipulator when the manipulation of the manipulator is valid is equal or smaller than a threshold, the controller controls a movement of the lens from an initial position that is the position of the lens when the manipulation of the manipulator is invalid. When the manipulation of the manipulator becomes valid and the difference is larger than the threshold, the controller controls a movement of the lens from an initial position that is the position of the lens corresponding to the manipulator's position detected by the manipulator position detector.
