ABSTRACT:
Apparatus is disclosed suitable for installation in a camera for optimizing the relationship of the image surface of the camera relative to the image receiving surface, such as film, of the camera for different adjustments of the focusing lens and the aperture setting. The adjustment is made by moving the image receiving surface, i.e., the film, to a best fit relationship to the image surface of the lens, with the movement of the film being made after the trip button of the camera is depressed and with the adjustment of the extent of movement of the film being instantaneously responsive to the positions of the focus and aperture settings. The apparatus disclosed is also suitable for use in a general purpose camera as a mechanism for flattening and holding the film in a fixed, predetermined position.
