Abstract
A camera having alternately selectable shutter release priority and focus control priority modes of operation. In the shutter release priority mode, operation of an automatic focusing device is inhibited when the shutter is actuated, and the shutter may be released irrespective of whether the photographic image is in focus. In the focus control priority mode, the shutter cannot be released unless the image is in focus. When the camera is in the shutter release priority mode, photographs may be taken in rapid succession without regard for precise focusing.
