Abstract

950,738. Photo-electric exposure meters. VOIGTLANDER A.G. June 1, 1960 [Dec. 3, 1959], No.19472/60. Heading G1A. Two rotatable annular screens coupled respectively to an exposure time or aperture setting member and a film speed setting ring limit the light falling on the photo-cell of a camera exposure meter. Shading areas 26, Fig. 3, of the screen 25 co-operate with the areas 29, Fig.4, of screen 28, to form variable screens in three windows 16, Fig. 5, located in front of three photo-cells equally spaced around the shutter housing. The light falling on the cells depends upon film speed and exposure time or aperture.- The photo-cell output respectively indicates aperture or exposure time and this is set manually, semi-automatically, or automatically in known manner. German Specification 730, 288 is referred to.
