PURPOSE:To prevent the occurrence of exposure errors by obtaining quide number information from aperture value, object distance and ASA sensitivity and feeding the divided pieces of guide number information to plural strobe devices. CONSTITUTION:A strobe device distributing adapter 47 is provided removably to a camera body 15 and strobe devices 48, 49 are mounted to the adapter 47. A mode changeover switch 37 selects respective modes of guide number control, automatic strobe control and dimming signal control. An LSI 24 is incorporated into the body 15 and ASA numerical value information and aperture numerical value information are fed to an n-bit parallel adder ADD1 and object distance numerical value information is fed to an n-bit parallel adder ADD2. In the ADD2, the input information is doubled and the output information of the ADD1, 2 is added ADD3 and the results of the addition are converted to decimal information by a decoder DE. The said information is then fed to the adapter 47, from which the divided pieces of guide number information is fed to the respective devices 48. 49. |
