PROBLEM TO BE SOLVED: To execute an automatic light control action without depending on the reflectivity of a film when a flash-photographing action is executed by providing a camera with a light control element executing a photometry action in order to obtain data for controlling light by using the light of a part of luminous flux for a finder. SOLUTION: This camera is constituted so that a diffusion plate P1 is arranged at the position of a primary image surface I1 and provided with the element for controlling light SL executing the photometry action in order to obtain the data for controlling light by using the light from the plate P1. Besides, it is provided with a photometry element SE executing the photometry action of steady light by using the luminous flux fetched as one part of the luminous flux for a finder by splitting the luminous flux for a finder by a half mirror HM2. Since the primary image equivalent to an image formed by luminous flux for photographing is formed on the plate P1, the focusing state of a photographing optical system can be confirmed through a finder. Then, since the plate P1 is used, the focusing state of the photographing optical system is confirmed. Besides, since the light reflected from a film surface N1 is not used, a correcting action corresponding to the type of the film need not be executed. |
