Camera photometer

   
   

Light beams, reflected on an outer surface around a lens barrel which may be incident to a light receptor, are intercepted at a maximum by a camera photometer embodying a light shield mask having a wide range light shield formed to intercept light over a wider range at a part near a lens barrel when the light receptor of an AE device is arranged in the vicinity of the lens barrel. The light shield mask is an elastic thin member stuck onto the incidence surface of the condenser lens of the photometer and has an opening formed to be partly like a circular arc but along a chord of the circular arc elsewhere to form a wide range light shield outside the chord.
