Abstract

PURPOSE:To perform flash photographing as well as general EE photographing, by performing respective operations automatically by transferring information from a flash device side to a camera side. CONSTITUTION:A signal from the charge end signal output device 23 of a flash device B turns on the electric charge display device 6 of a camera A, and switching devices SC1 and SC2 are changed over to connect a shutter-second setter 4 to a second-time controller 5. On the other hand, an aperture controller 11, an aperture display device 13, and alarm device 16 and 18 operate in response to the output signal of an aperture information output device 24 to perform aperture control, display and warning adequate for flash photographing. When a shutter operates in a second time suitable for the flash photographing through release operation, a synchro swtich 1 operating synchronizing with the shutter triggers the flash device B, which emits a flash while the quantity of emitted light is controlled according to a subject's distance, thus performing proper exposure.
