Patent ID: 8755128

Claim:
An image pickup lens comprising: an optical system including a lens; a controller configured to control a movement of the lens in an optical axis direction; a lens position detector configured to detect a position of the lens; a manipulator configured to accept a manipulation used to move the lens; and a manipulator position detector configured to detect a position of the manipulator, wherein the controller has a manipulator valid mode of controlling the movement of the lens according to the position of the manipulator and a manipulator invalid mode of controlling the movement of the lens not according to the position of the manipulator, and wherein, in the manipulator valid mode, in a case that a difference between the position of the manipulator when the manipulator invalid mode was started and the position of the manipulator when the manipulator valid mode was started is equal to or smaller than a threshold, the controller is configured to set an initial position of the movement of the lens to the position of the lens detected by the lens position detector when the manipulator invalid mode was started to control the movement of the lens, and in a case that the difference is larger than the threshold, the controller is configured to set the initial position of the movement of the lens to the position of the lens which corresponds to the position of the manipulator detected by the manipulator position detector to control the movement of the lens.
