ABSTRACT:
A way of "customizing" a standard single lens reflex camera that uses perforated film to include four film registration pins for precisely aligning the film frame with respect to the film aperture. These four pins control the position of the film and eliminate skewing. The pins engage the perforations in the film except during film transport. Also included is a non-contact frame counter that utilizes the perforations to indicate frame count and film movement.
