ABSTRACT:
Disclosed is a reflector for an electronic flash device capable of changing the illuminating angle. The reflector is nearly of elliptical shape as in the case of the conventional one, wherein the ratio of the longer diameter of the ellipse to the shorter one and the shorter diameter itself are set at special values. Thus, the reflector can be designed small, while the same illuminating angle as in a case where a wide angle adapter is mounted on the flash device can be obtained.
