In a camera system comprising a camera and a flash device, a first synchronizing signal is generated when the camera shutter starts an exposure, and a second synchronizing signal is generated when the exposure is about to be terminated. First and second synchro control modes may be selected. A light emission control is responsive to the first synchronizing signal to drive the flash device when the first synchro control mode is selected and is responsive to the second synchronizing signal to drive the flash device when the second synchro control mode is selected. A shutter control makes possible the driving of the shutter at shutter speeds up to a first limit speed when the first synchro control mode is selected and makes possible the driving of the shutter at shutter speeds up to a second limit speed when the second synchro control is selected, the second limit speed being lower than the first limit speed. |
