A lens apparatus which has a small size but allows a higher magnification and an image-pickup apparatus including the lens apparatus are disclosed. The system includes a classification module, a controller, a determination module, a ratio module and a score module. The control target device is connected to the information processing apparatus. A portion of the connector may be selectively deflected radially out from a remainder of the connector in response to expansion of the expandable structure disposed inside the connector. The abutting end abuts with the pushing surface of the clutching switch. Alternately, slideable members may allow the support member to be selectively retracted and extended to provide the desired vertical position adjustment.
