Abstract
542,329. Cameras with exposure meters. ZEISS IKON AKT.-GES. July 10, 1940, No. 11503. Convention date, Oct. 18, 1938. [Class 98 (i)] In a twin-lens camera having an extensible part 4 which carries the lenses and provided with a photo-electric exposure meter, the whole of the parts constituting the meter, or alternatively these parts which cooperate with the exposure time and stop adjusting means, are arranged on the part 4. As shown, the meter 1 is arranged on the upper side of the part 4, so that it may be read from above. The shutter speeds are adjusted by a knob 5 which simultaneously adjusts a resistance in the meter circuit and coaxial with the exposure objective. The stop is adjusted by a knob 2, which also adjusts a contact along the resistance.
