Abstract
A flash photography system with a camera body and an electronic flash device incorporates first to third terminals in the camera body which are connectable to fourth through sixth terminals in the flash device. A signal is produced to distinguish between first and second modes wherein data is transmitted to the electronic flash device and data from the electronic flash device is transmitted to the camera body, respectively, and connected to the first terminal. Clock pulses control the data transmission and data is read from the electronic flash device and transmitted to the electronic flash device through the second terminal in response to the clock pulses. An initiating signal to cause production of artificial illuminating light from the electronic flash device is provided at the third terminal. In response to the distinguishing signal, selection is made between the first and second modes via the fourth terminal. The electronic flash device provides via the fifth terminal serial data to the camera body in response to the clock pulses through the fourth terminal. Data is read to the electronic flash device through the fifth terminal in response to pulses from the fourth terminal. The electronic flash device provides artificial illuminating light in response to the initiating signal through the sixth terminal.
