Abstract

1,178,663 Camera view-finders. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Jan. 18, 1968, No.2685/68. Heading G2A. A camera view-finder comprises a front lens 1 and eye-piece lens 2. Outside the system is a lamp or other device 4 indicating an exposure-setting value. Lens 1 is formed with two reflecting surfaces 7, 8, so that light from 4, after passing through a diaphragm 5, is reflected so as to pass through lens 1 transversely to the optical axis, and then back through the eye-piece. Figs.2, 3 (not shown) are modifications in which the light passes through the eye-piece lens transversely to the optical axis.
