ABSTRACT:
A camera system includes a camera main body, a transmitter for transmitting a signal to a flash device, a single communication path between the camera main body and the flash device, and a receiver for receiving a signal from the transmitter. The signal received by the receiver is selectively switched by a selector in the receiver in accordance with communication control data or emission control data with respect to the flash device. The selector switches the communication path to the emission control side only when data representing that the communication path is used as a signal path for emission control data with respect to the flash device is transmitted.
