Abstract: A photometer includes a luminous flux splitter that splits a luminous flux incident from a single light receiving optical system and guides the luminous flux to a finder optical system and a photometric part. A light receiver is arranged at a position to receive at least a part of light split into the finder optical system by the luminous flux splitter and generates an output for light emission profile analysis according to a light reception result.
