Abstract
A camera equipped with an electronic shutter having an automatic focus detecting device capable of automatic focusing of the photographing lens through detection of the distance between the object being photographed and the camera comprises an electronic module for the automatic focus detection system, an electronic module for the automatic exposure control system, an electromagnet connected to both of the electronic modules, and an obstructing means capable of constraining the electromagnet at a first position during the course of displacement of the electromagnet from a first position to a second position. According to the camera release operation or the operation caused by the camera release operation, the electronic module for the automatic focus detection system controls the electromagnet so as to determine the focus position and the electronic module for the exposure control system controls the electromagnet so as to adjust the exposure after the electromagnet is constrained by the obstructing means at the first position.
