Abstract
For use in a sound motion picture camera adapted to handle both sound and lent film and having a driven capstan at the sound station thereof, the capstan drive motor is used to power a driven component of an automatic focusing system by which a focusable objective lens can be focused automatically on a remote subject. By a control switch, associated with the camera operation control member, either manual or automatic focusing modes can be selected, the automatic mode being further selectable as being continuous during film transport operation or limited to a period before film transport operation begins.
