Abstract
1524096 Camera exposure indicator PENTACON DRESDEN KAMERA-UND KONOWERKE VEB 3 June 1976 [12 June 1975] 22958/76 Heading G2A A camera exposure indicator has a row of lights 2 to 6 visible in the viewfinder 1, the central light 2 remaining permanently on, lights 3 and 4 being turned on at different degrees of under exposure and lights 5 and 6 being turned on at different degrees of over exposure. When the correct exposure is set only light 2 is on. Preferably light 2 is a different shape and colour from the other lights. As shown, lights 3 to 6 are controlled by a circuit (7), Fig. 2 (not shown) connected to a photoconductor (9) and a resistor (8). The photoconductor (9) is located behind a diaphragm (10) coupled to the lens diaphragm. The resistor (8) is coupled to exposure time and film speed setting members.
