Abstract

PURPOSE: To mount a usual photographing lens on an autofocusing camera body so as to automatically drive a shutter at the time of focusing by executing a logical operation between an enable signal and a focusing detection signal from a focusing means, outputting a shutter driving signal and driving the shutter.
CONSTITUTION: The titled device provides a means 207 for generating the enable signal at the time of setting a mode changeover switch 203 in a single mode, a logical operation circuit 209 which executes the logical operation between the enable signal and the focusing detection signal from the focusing means and outputs the shutter driving signal and a driving circuit 211 which drives the shutter by the logical operation circuit 209. Since the shutter is automatically driven at the time of focusing on an object, a kind of photographing by means of an autofocusing (AF) function can be executed even if the usual photographing lens having no AF function is mounted on the autofocusing (AF) camera body.
