CONSTITUTION: When the rotation of a lens holder is continued, the energizing force of a toggle spring 67 acts in a direction where the counterclockwide rotation is promoted from the middle of the rotation and the rotation is stopped in a state where a sector 65 abuts on a stopper 58. At such a time, a macro lens 14 is positioned on the photographing optical axis 13 and a target mark 19 is interposed in a finder 18. In such a state, the lens holder is positioned and fixed between the toggle spring 67 and the stopper 58. Since the mark 19 is observed in detail by the diffraction phenomenon of object light, the center of the object is caught in the aperture of the mark 19. Thus, the compensation of parallax is performed by taking the mark 19 as the reference.
