Abstract

PURPOSE: To adjust the opening to the specified aperutre value corresponding to the flash device, in the case of dimmer type flash photographing, by providing a signal forming means to form plural specified aperture value signals in cooperation with the specified aperture signal source provided outside of camera main body.
CONSTITUTION: When a flash device 1 is fitted to a shoe 6 of a camera 3, an end part 7-1 of a lever 7 is pushed and displaced by a protruding part 2 forming a specified aperture signal source. As a result, S2-1 of a switch S2 is changed over to S2-2 side, and a variable resistor R1 of which value is set by a sliding brush 7-2 fitted to a lever 7 is connected instead of a photo detector P. Therefore, when the specified aperture of the attached flash device 1 is, for instance, F4 at ASA100, the value of R1 corresponds thereto, and corresponding current flows in a meter M, so that the pointer automatically indicates F4. In this way, when performing flash phtotgraphing, since the specified aperture to be set will be set automatically depending on the characteristics of the flash device and sensitivity of film, there is no risk of misoperation.
