<p>PURPOSE:To execute photographing and data transfer under a required exposure control without remodeling a camera by fitting a data transfer device having an exposure operating function freely attachably/detachably to the back cover side of the camera to send its operated result to a camera body. CONSTITUTION:The individual data transferring device is fitted freely attachably/detachably to the back cover side of the camera body having an automatic exposure control function. The transferring device has a back circuit BCKC having an operating function for plural automatic exposure control modes including the exposure control mode of the camera body, executes exposure arithmetic at a required exposure control mode on the basis of photometric data and film sensitivity data obtained from the camera body and sends the operated result to the camera body. Consequently, photographing and its data transfer can be attained under a required exposure control mode different from that of the camera body without remodeling the camera body.</p> |
