EINAEUGIGE SPIEGELREFLEXKAMERA MIT EINER DIE BELICHTUNG SELBSTTAETIG STEUERNDEN SCHALTUNG

摘要

A single lens reflex camera with an automatic exposure control circuit includes a photodetector and a light emitting indicator in the viewfinder optical system. The light emitting indicator is energized to emit light with high luminance for a predetermined period when the electric power source is turned on in the camera. By the high luminance light emission of the light emitting indicator, the photodetector in the exposure control circuit is preliminarily exposed to light before it starts to measure scene brightness. Thus, the response of the photodetector is enhanced.
