Abstract

PURPOSE:To eliminate photometry difference between controlling and displaying by nearly equalizing the photometric sensitivity distribution of a photodetection part for exposure control for a shutter curtain surface and a film surface to that of a photodetection part for display for a reflecting plate for display photometry. CONSTITUTION:The photometric sensitivity distribution of a photodetecting element 11 for exposure information display is nearly equalized to that of a photodetecting element 12 for exposure control for a shutter curtain surface and a film surface through a condenser lens 13 and a condenser lens group 14. In this case, the light distribution characteristics of the photodetecting element 11 through the condenser lens 13 are difference from those of the photodetecting element 12 through the condenser lens group 14 within a distance to a reflecting surface because of a difference in diffusibility, etc. Consequently, there is no photometry difference generated between exposure controlling and displaying.
