See full text

A photometric circuit for a camera has a photo-electric conversion element arranged to measure light in the middle part of the angle of view of the camera and a plurality of photo-electric conversion elements arranged to measure light in the peripheral parts of the angle of view. Of these peripheral light measuring elements, the elements disposed symmetrically with each other relative to the middle part of the angle of view are paired and connected in series with each other. Further, the series circuits thus formed are connected in parallel with the middle light measuring element.
