Electronic flash device

摘要

An electronic flash device which is pivotally movable about an axis intersecting the focal plane of a photo-taking lens and of which the light distribution is changed relative to the angle of view of a camera by pivotally moving comprises a light distribution setting device for setting the amount of light distribution, a posture detecting device for detecting the posture of the electronic flash device relative to the camera, a determining device for determining the amount of light distribution on the basis of a desired amount of light distribution set by the light distribution setting device and the posture detected by the posture detecting device, and a light distribution changing device for controlling the light distribution on the basis of the amount of light distribution determined by the determining device.
