Abstract

PURPOSE:To obtain a dim signal in spite of no execution of upward movement of a movable mirror or shutter operation by obtaining the incident light to photometric elements based on the light partly transmitted through the movable mirror and providing a test switch in parallel with a synchronizing contact. CONSTITUTION:This consists of a combination of a single-lens reflex camera of a TTL direct photometric system of reflecting the light transmitted through a photographic lens 3 on the shutter curtain plane and the film plane 6, and receiving the light reflected therefrom with photometric elements 5 of an exposure control circuit, and a TTL automatic strobe, wherein the incident light to the photometric elements 5 is obtained based on the light partly transmitted through a movable mirror 1, and a test switch SW2 for test emission of a flash discharge tube F is provided in parallel with a synchronizing contact. The trigger switch of the integrating circuit of the exposure control circuit is controlled of opening and closing by the emission signal generated with the light emission of the flash discharge tube F.
