を特徴とするストロボ同調装置。 In a camera equipped with an aperture blade having a mechanism to limit the maximum aperture position and a strobe with a fixed guide number, when a voltage is applied to an electrostrictive element whose amount of distortion is uniquely determined in accordance with the applied voltage. A mechanism is actuated to limit the maximum aperture position of the aperture blades by the distortion generated in the electrostrictive element, and the mechanism is adapted to correspond to the electrically input film sensitivity and the electrically input shooting distance. A strobe tuning device characterized in that the applied voltage to the electrostrictive element is determined by the following.
