Abstract
908,320. Photo-electric exposure control. AGFA A.G. Feb. 24, 1961 [Feb. 27, 1960], No. 6947/61. Class 40 (3). A single lens reflex camera has means for attaching interchangeable objectives, a rotating shutter and a semi-transparent mirror therebetween which directs light reflected back from the shutter on to a photo-cell. The angle of convergence of light on to the photo-cell is the same as that on to the film. Scene light passes through an interchangeable objective 10, shutter 5 and main objective 1 to a picture gate 3. A semi-transparent. mirror 6 directs scene light into the viewfinder 7 and light reflected from shutter 5 when it is obscuring the film, to a photo-cell 9. A lens 8 ensures that the convergence angles of light falling on the film 2 and photo-cell 9 are equal.
