Abstract

PURPOSE: To enable the electrical displaying of the dimming range corresponding to film sensitivity and aperture by the use of the results of the operating by operating the dimming range of the strobe from the control signals determined according to film sensitivity and photographing information.
CONSTITUTION: In the automatic strobe which stops light emission when the light reflected from the subject reaches the specified quantity according to film sensitivity and photographing information, the 5 output signals of a count decoder 12 correspond to ASA25, 50, 100, 200, 400 respectively and are supplied to respective AND gates 21W30, and the 2 output signals of a count decoder 16 corresponding to F4, F8 are supplied to the AND gates 21W30. In the initial state, the output signals corresponding to ASA100 and F4 are high level. When it is desired to change the film sensitivity, a shift switch 10 for ASA information is pushed and similarly for the aperture, a shift switch 14 is pushed, by which it is shifted between F4 and F8, thus the film sensitivity and aperture may be surely set.
