PROBLEM TO BE SOLVED: To provide a photometry lens in which the position of a light receiving element is easily adjusted in the photometry device of a single lens reflex camera. SOLUTION: This lens is a photometry lens 11 of a photometry device in which photometry is executed by receiving luminous flux transmitted through a finder screen 31 of the single lens reflex camera and emitted from a cavity pentagonal mirror 21. Then, an illumination light incident end surface 12 for guiding illumination light made incident from the ridge line direction of the mirror 21 to the light receiving surface 14 of a light receiving element 13 is formed on the lens 11. The illumination light made incident on the receiving surface 14 is reflected here to form the image of the receiving surface 14 on the screen 31 through the lens 11 and the mirror 21. |
