To integrate a photocurrent (Is), which is dependent on the brightness of an object to be photographed, an exposure control circuit for a camera is equipped with an integrated circuit having a plurality of integrating condensers (20 to 23). The integrated voltage (Vo) is compared with a decision voltage (Vj), which depends on a particular value of the film speed. The value of the decision voltage is switched either manually or automatically for low and high film speeds, when the combined capacity of the integrating condensers (20 to 23) is switched. <IMAGE>
