ABSTRACT:
An apparatus for precisely moving a camera lens element to focus an image at the camera's film plane is disclosed. The apparatus employs an electrically controlled and incremently stepped rotating motor which moves a lens element parallel to the lens axis. The disclosed motor is an epicyclic motor, and a mechanical coupling arrangement interconnects a driven rotating motor element and the lens element holder and converts the rotary motion of the motor to incremental translation of the lens element. The apparatus moves the lens element in this manner in small precisely controlled increments, for example, steps of less than 0.001 inch.
