ABSTRACT:
A selection device which permits or prohibits serial communication is provided in a lens apparatus capable of performing serial communication to suppress the serial communication although a camera body can perform the serial communication. Thus, a safe operation of the system can be guaranteed. At the same time, the processing speed of the processing circuit in the lens apparatus can be reduced, thereby successfully reducing the power consumption.
