ABSTRACT:
A luminance detecting module and an focus detecting module are actuated in the first step of shutter release operation and an exposure control module is actuated in the second step. All of these modules are connected to a single electromagnet. When a photographing impractible signal is given in the first step of the shutter release operation, the electromagnet actuates a release locking member so that the shutter release motion is interrupted.
