The zoom lens has a motor drive mechanism for driving the zoom mechanism to move the zooming lens unit in the optical axis direction, a lens controller for controlling the drive of the motor drive mechanism, a switching mechanism for performing a predetermined control operation on the lens controller, and a lens input and output device for effecting data communication with the camera body. The camera body has a body controller for controlling operations of the entire camera system, and a body input and output device for effecting data communication with the zoom lens through the lens input and output device.
