Abstract

PURPOSE:To eliminate intricate mechanisms and errors and perform automatic focusing accurately by so constituting a device that a transparent range finding element is provided on the focal plane of a film or focal glass. CONSTITUTION:This is so constituted that a range finding element 8' is provided on the surface of a transparent range finding element substrate 8 in close contact with a film plane 7. It is equally well to form focal glass 3 onto its focal plane 3' and to mount said element thereon. With such constitution, not only the accurate range finding is made directly without hindering the optical path because the transparent range finding element is transparent, but also intricate mechanisms are eliminated. Dynamic photographing is also made possible in real time.
