ABSTRACT:
This invention relates to a reflex camera device having a single lens for the photography of right and left images from an object space transmitted as first and second light ray bundles from two positions separated by an interocular distance onto a single frame of a single film strip; a first exterior means for distinguishing from each other the first and second light ray bundles; a single frame aperture; a second means near the image plane to separate the first and second light ray bundles from each position respectively into right and left adjacent images onto the single frame; means to control convergence, focus and interocular distance; and a reflex viewer containing a third distinguishing means near the image plane to enable the simultaneous viewing and photographing of right and left adjacent images; and optionally an indicium marking means for said film strip at the side of the frame line.
