ABSTRACT:
A photometric assembly of the reflective photometry type is provided in which light passing through a taking lens and reflected by a blind surface of a shutter or a film surface is directed by a reflecting member so as to be incident on a photometric, photoelectric transducer element disposed on a printed circuit board. A shield member is disposed to prevent the direct incidence of the reflected light from the blind surface or the film surface onto the transducer element.
