摘要： A reflex camera having a photoelectric exposure meter includes a light concentrator guide having reflective surfaces mounted on and arranged behind the reflex mirror which is partially transparent (half silvered). The light concentrator guide is provided with a first reflective surface lying transversely of the optical axis of the object lens of the camera and a second reflective surface lying transversely of the optical axis. The second reflective surface reflects light rays entering the light concentrator guide from the object lens of the camera towards a light emergent surface thereof. A photoelectric receiver is situated opposite the light emergent surface of the light concentrator guide to receive the light rays.
