Abstract
Provided is a distance measurement and photometry apparatus used in a camera or the like, which sets a distance between distance measurement sensors and distance measurement light receiving lenses and a distance between a plurality of photometry sensors and photometry light receiving lenses such that a position of a region within the observation field in which information is obtained by the distance measurement sensors is equal to a position of a region within the observation field in which information is obtained by the photometry sensors irrespective of a distance to the measurement object. With this construction, it can be prevented that a distance measurement region in which the measurement object is captured and a photometry region provided corresponding to the distance measurement region are shifted with respect to each other even when the set measurement object is located at any distance.
