Abstract

PURPOSE: To let the exposure determination of the desired portion of the subject be effectively accomplished in photographing by providing a device which is changeable of photometric range in the photo detecting part of the automatic camera.
CONSTITUTION: A photometric range change lens group 11 is disposed to the front of the photo detector 9 of the automatic camera. The lens group 11 is connected to a knob 21 by way of an interlocking mechanism. Now when a knob 21 is turned to the "center-weighting" position, the center photometric lens is set in front of the photo detector 9. The light passed through the lens 6 of the camera body is reflected by a shutter curtain 8, passes through the center-weighting lens and is entered to the photo detector 9. To a measured value memory element 100 are inputted both data of exposure and photometry of center-weighting position. The data integrating these are displayed in the finder. This constitution permits the effective determination of the exposure of the desired portion of the subject.
