Abstract

PURPOSE: To enlarge the range of photography by changing the flash auto system and the adjustable light flash system.
CONSTITUTION: In case the photographing distance is within the interlocking range of the specified value of diaphragm, change switch 15 is connected to contact 15a via distance ring which finds the range so as to make transistor 23 conductive via constant voltage circuit 13, hence photography of adjustable light flash system by means of the adjustable light of flash of flash tube 21 is carried out. In case the photographing distance is out of the interlocking range, the switch 15 is changed to contact 15b so that the diaphragm value is programmed, hence photographing by flash auto system is done to enlarge the range of photographing at the time of flash photography. Further, the photographing system is discriminated by lighting display lamps 16, 17 of different color of light emission
