PROBLEM TO BE SOLVED: To provide a photometry device capable of positionally adjusting a photodetector with high accuracy and shortening an adjusting time, in a photometry device whose photometric sensitivity distribution is gentle. SOLUTION: The photometry device provided with a photometric lens 11 and the photodetector 13 is for executing the photometry of the finder screen 31 of a single lens reflex camera. The photometric lens 11 and the photodetector 13 are provided so that a transparent parallel flat plate 17 can be inserted between the photometric lens 11 and the photodetector 13 and when the parallel flat plate 17 is inserted, the focusing screen 31 and the light receiving surface 14 of the photodetector 13 are in nearly conjugate relations. |
