This invention allows measuring the spectral state of an object more accurately even at low luminance, and implementing high-precision focus detection. A photometry apparatus includes a diffusing optical member which is inserted in the optical path of a photographing lens and has a diffusing surface, and a light unit which receives diffused light having passed through the diffusing surface, and has a first light receiving portion, and a second light receiving portion whose receivable light energy is smaller than that of the first light receiving portion. The first and second light receiving portions are so arranged as to make the parallax of the second light receiving portion with respect to the optical axis of the photographing lens smaller than that of the first light receiving portion.
