Abstract
The present invention relates to an exposure control system for a camera with both priority modes in which the photographic information of either the shutter time or the aperture value and the photographic information including the measured value of the brightness of the object to be photographed are processed so as to obtain a proper exposure value. The system is characterized in that either an optional shutter time or an optional aperture value is set by a common set means, for example, a dial in such a manner that the output of the set means is put in the operation means so as to control the exposure amount. Further, the condition showing whether the value set by the common set means is the aperture value or the shutter value is clearly indicated.
