PRISMENSUCHER FUER SPIEGELREFLEXKAMERAS MIT BELICHTUNGSMESSER

摘要

The subject of the invention is a prism viewfinder for reflex cameras with built-in exposure meter means. It is of the known kind in which the prism has a bevel face reflecting the received image on to a mirror face which in turn reflects in to an eyepiece and a light-sensitive element of the exposure meter means adjacent to this eyepiece. In the present invention the image is also reflected by the mirror face on to an additional plane face and immediately adjacent the light-sensitive element, thereby giving an enhanced image and improved exposure measuring results.
