ABSTRACT:
A photometric device includes split photometric sensors for photometrically measuring a plurality of different split regions of a subject image formed by photometric optical systems. The split photometric regions of each split photometric sensor are formed in such a manner as to partially overlap with the split photometric regions of the other split photometric sensor. The photometric optical systems defocuses the images so that the combined photometric sensitivity distribution changes smoothly from the center of the subject region toward a periphery thereof.
