ABSTRACT:
A camera system comprises an operation member provided in an interchangeable lens adapted to be manually operated; a signal sending circuit for sending a signal in response to the manual operation of the operation member; and a controller provided in a camera body which is adapted to switch between an operative state where a predetermined operation is executed and a halt state where the controller is halted after completion of the predetermined operation. The controller switches from the halt state to the operative state in response to the signal from the signal sending circuit to execute the predetermined operation. According to the camera system, since the system controller in the camera body is actuated in response to the operation of the member on the lens side, a camera which can substantially instantaneously respond to a request on the lens side can be realized.
