A flashmatic device for cameras equipped with a programmed electronic shutter having sectors serving also as diaphragm blades, firing the flash at a suitable point in a phase of the shutter operation in which the aperture is gradually opened, to ensure synchronized flash shooting. Even in a case where a sector closing signal is produced earlier than a flash trigger signal, the flash is fired by means of a switch which is closed in relation with the sector closing motion to make flash synchronization possible under any condition. |
