An automatic exposure control camera wherein the aperture preset ring in the photographic lens of the electromagnetic aperture control system for controlling the automatic aperture mechanism by means of the electromagnetic attracting means is charged at the totally opened position by means of the driving mechanism at the side of the camera every time a photograph is taken. By means of the shutter release operation, the aperture preset ring is moved from the totally opened position to the most closed position so as to determine the aperture value of the aperture preset ring. The camera is provided with a means for making the aperture preset ring rotatable up to a certain determined aperture value by operating the release member of the automatic exposure control operation by means of the control member of the automatic aperture mechanism operated and, in turn by means of the diaphragm closing operation means whereby the depth is confirmed by the diaphragm closing operation with the diaphragm closing operation means.
