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.
