PURPOSE: To enable the photograph of the next best condition to be obtained even when exposure is deficient by forcefully closing the shutter within the hand blur limit second time based onthe signal by the flash light of a strobe.

CONSTITUTION: A current detecting memory logic circuit, timer pulse generating circuit and electric shutter control circuir are provided to the electric circuits of the connected. The potential at the emission of a flash discharge tube 62 is stored in a NAND circuit. The shutter control circuit is connected with the series circuit of a light emitting element 234 disposed alongside a photo detector 203 for photometry, a resistance 288 and a switching transistor TR 233 and the series circuit of a photometric circuit 302, a TR 260 and a shutter closing magnet Mg between the lines E01, E02. The circuit 302 causes the TR 260 to go OFF to close the shutter when the element 203 receives more than specified quantity of light.
