A sub-standard motion picture camera has two selectively operable lens systems, one of which is a main lens system for obtaining a normal shot, and the other is an auxiliary lens system for obtaining a closeup shot or tilting. To provide the auxiliary lens system, the camera has in its housing an opening or a light opening within which an auxiliary lens is disposed, the opening being closed or opened properly to render the auxiliary lens system operative or inoperative. |
