    • A zoom lens system for a camera comprises a focusable lens, a variator lens for making a focal length of the lens system variable and a compensator lens for compensating the displacement of its image point caused by the variator lens. A zoom operating sleeve is provided which is rotatable about an optical axis and formed on its inner surface with first and second cam surfaces according to which lens holders for the variator and compensator lenses are respectively controlled in relative movement with the aid of a spring for resiliently urging the lens holders against the cam surfaces.
    • 用于相机的变焦透镜系统包括可调焦透镜,用于使透镜系统的焦距变化的变倍透镜和用于补偿由变倍透镜引起的其图像位移的补偿透镜。 提供变焦操作套筒,其可以围绕光轴旋转并且在其内表面上形成有第一和第二凸轮表面,根据该第一和第二凸轮表面,借助于用于弹性的弹簧分别控制用于变速器和补偿器透镜的透镜保持器相对运动 将镜头保持器推向凸轮表面。
