装置。 In a camera with a variable magnification function of the photographic lens,
A light-receiving aperture member is provided in front of the light-receiving element for photometry so as to be movable in the optical path direction, and as the photographic lens is switched to the wide-angle side, the light-receiving aperture member approaches the light-receiving element for photometry, and the photographic lens is moved to the telephoto side. The light-receiving diaphragm member in the camera is linked to a moving member that moves as the magnification is changed so that the light-receiving diaphragm member moves away from the photometric light-receiving element as the light-receiving diaphragm member moves away from the photometric light-receiving element. acceptance angle switching device.
