ラのファインダー倍率切替装置。[Scope of Claim for Utility Model Registration] The main finder system is formed by the first objective lens, the second objective lens, the half mirror, and the eyepiece, and the daylight finder system is formed by the light diffuser plate, the field frame holding plate, and the mirror. In a daylight-type bright frame finder, the first objective lens is retracted to a retracted position between the light diffuser plate and the field frame holding plate in conjunction with switching of the focal length of the photographing lens, and at the same time the second objective lens is retracted to a retracted position between the light diffusion plate and the field frame holding plate. A viewfinder magnification switching device for a camera, characterized in that the camera is moved back to a retracted position on the eyepiece side.
