Zusammenfassung:PURPOSE: To provide a photometry device capable of accurately measuring a photometric value at the optional spot of a subject regardless of a photographing condition. CONSTITUTION: Photometry in all the area of a photographic image plane is performed by bisected photometry sensors 17a and 17b provided near the ocular part of a finder optical system, and reflected light from all the surface of film which is being exposed is received by direct photometry sensors 20a and 20b, then the evaluation light control of a stroboscopic device 202 is controlled by a CPU14 based on output from the sensors 20a and 20b. Furthermore, photometry in a part of the photographic image plane is performed by spot photometry sensors 13a and 13b provided on the same surface as a range-finding sensor 204 for measuring a distance to the subject.
