ABSTRACT:
A flash illumination device is removably mounted on the body of an accompanying camera. Electric adjusting means set the diaphragm of the camera. A signal system produces a signal corresponding to a prescribed diaphragm setting and transfers the signal through a shoe attached to the camera body or through other electric connecting means. When the flash illumination device is connected to the camera body, the signal system provides an electrical signal which causes the adjusting means automatically to set the diaphragm.
