<p>A combined view and rangefinder for use in cameras having a variable focus objective lens includes means for establishing a primary image of the scene to be photographed framed in a generally rectangular field of view together with a secondary focusing image superposed on the primary image and movable obliquely across the primary image in correspondence with camera focusing so that substantial coincidence between the primary and secondary images is indicative of the camera assuming a focused condition with respect to the scene to be photographed. In addition, the path of movement for the movable secondary image of the combined view and rangefinder is located above the geometric center of the primary image so as to facilitate the framing of a human photographic subject to locate the subject's head above the geometric center of the picture. The combined view and rangefinder may also be conveniently and easily assembled through snap-fitted components.</p> |
