Photographic apparatus with dual function sonic transducer

An autofocusing camera having an ultrasonic ranging system, formed in part by a sonic transducer, for measuring subject distance is provided with an audio system which incorporates the same sonic transducer for providing the camera operator with audible information, such as warning signals indicating that the camera is out of film or that the flash illumination system is not in its operative or ready state.
