A camera system is provided that permits memory data dedicated to particular camera accessories to be transmitted to the camera body for enabling the operation of the camera. The camera accessories can carry dedicated information or variable information to the camera body. Synchronization between the camera accessory and the camera body can be provided by a train of clock pulses. Information can be programmed in a fixed memory circuit to insure that only a particular accessory so designated will provide information to the camera body to prevent any erroneous inputting of data from a plurality of camera accessories that are contemplated for use with a particular camera body.read more
