Abstract

PURPOSE: To eliminate error in aperture setting due to use of films of different sensitivities, by controlling the aperture control device on the basis of information from a specified aperture information source provided in a dimmer type flash device and the information from a film sensitivity setting means.
CONSTITUTION: When a dimmer type flash device 1 having a protruding part 2 of which length is determined according to the specified aperture attached to the mounting base thereof is fitted to a shoe 6 of a camera, a lever 7 displaces to change over a switch S2, and a variable resistor R1 is connected instead of a photo detector P. Then, the value of R1 becomes the value corresponding to the specified aperture of the flash device 1 to pass current into a meter M, and the aperture is automatically set by a sawtooth 5 of the EE mechanism intended to set the aperture of camera automatically. Thus, by fitting the flash device, the aperture value to be specified is automatically set even if replaced with a film of different film sensitivity, so that error in aperture setting may be completely prevented.
