a variable magnification viewfinder optical system having a movable variable magnification lens group that changes the viewfinder field of view according to the focal length of the zoom lens system; a zoom motor that moves the variable magnification lens group of the zoom lens system; A lens shutter type zoom lens that is movably disposed above the optical system and includes a cam plate that moves the variable magnification lens group of the variable magnification finder optical system in conjunction with the variable magnification operation of the zoom lens system by a zoom motor. In the camera, the finder optical system is provided with a focal length display plate provided with a letter example indicating the focal length of the zoom lens system, and a pointer that moves along the letter string, and the pointer and the cam plate are linked. A focal point of a lens shutter type zoom lens camera, characterized in that the pointer is linked via a mechanism so that the pointer points to a letter indicating the current focal length of the zoom lens system in conjunction with the zooming operation of the zoom lens system. Distance display device. (2) In paragraph 1 of the claims for utility model registration,
A pointer is formed on a pointer plate slidably provided in a direction orthogonal to the optical axis of the finder optical system, and a cam plate and the pointer plate are connected by a lever rotatably pivoted between them. A focal length display device for a linked lens shutter type zoom lens camera.
