載の可変焦点カメラ用外付ストロボ。[Scope of Claim for Utility Model Registration] (1) In an external strobe attached to a camera that moves the built-in strobe in conjunction with changing the focal length of the photographic lens, detection for detecting light emission from the built-in strobe. means, a discharge tube that starts emitting light in response to a detection signal from the detection means, and a discharge tube that receives reflected light from a subject illuminated by the light emission of the discharge tube, and detects the discharge tube based on the amount of light received. a light emission stop means that outputs a light emission stop signal to stop light emission; and an adjustment means that controls the light emission stop means in conjunction with the movement of the built-in strobe, and the light emission amount of the discharge tube is adjusted to the focal length of the photographing lens. and the amount of received light. (2) The adjustment means is a filter that moves in conjunction with the built-in strobe and adjusts the amount of light reflected from the subject that enters the light emission stop means. An external strobe for a variable focus camera as described in item 1.
