    • The aspherical zoom lens of the invention includes sequentially from an object side: a first lens group which has a positive refractive power and is fixed relative to an image plane; a second lens group which has a negative refractive power and is movable on an optical axis of the aspherical zoom lens so as to have a magnification changing function; a third lens group which has a positive refractive power and is fixed relative to the image plane so as to have a light converging function; and a fourth lens group which has a positive refractive power and is movable on the optical axis so that the image plane displaceable in response to travel of the second lens group and movement of the object is fixed at a position spaced by a predetermined distance from a reference face. An air space is provided between the third and the fourth lens groups. When viewed sequentially from the object side, the first lens group includes a negative lens, a positive lens and a meniscus positive lens, the second lens group includes a meniscus negative lens, a double concave lens and a positive lens, the third lens group includes a single lens having at least one aspherical face and the fourth lens group includes a cemented doublet and a positive lens, at least one of which has at least one aspherical face.
    • 本发明的非球面变焦透镜从物体侧依次包括:具有正折光力并相对于像面固定的第一透镜组; 第二透镜组,其具有负屈光力并且可在非球面变焦透镜的光轴上移动以具有倍率变化功能; 第三透镜组,其具有正的折光力并相对于像面固定以具有聚光功能; 以及第四透镜组,其具有正折光力并且可在光轴上移动,使得响应于第二透镜组的移动而移动的像面和物体的移动被固定在与 参考面。 在第三透镜组和第四透镜组之间设置空间。 当从物体侧依次观察时,第一透镜组包括负透镜,正透镜和弯液面正透镜,第二透镜组包括弯液面负透镜,双凹透镜和正透镜,第三透镜​​组包括 具有至少一个非球面的单透镜和第四透镜组包括胶合双面和正透镜,其中至少一个具有至少一个非球面。

    • Provided from the object side are a first lens group (11) having a positive refracting power and fixed to the image plane, a second lens group (12) having a negative refracting power and a magnification varying action exhibited when moving along the optical axis, a third lens group (13) fixed to the image plane and having a positive refracting power, and a fourth lens group (14) movable along the optical axis so as to maintain the image plane moving with the movements of the second lens group (12) and of the object in a fixed position from a reference plane. Hence the movement of the image due to camera shake is corrected by moving the whole third lens group (13) vertically to the optical axis. The size is reduced and the aberrations are small because the whole groups whose optical performance is united are decentered.
    • 从物体侧提供具有正折射率并固定在像平面上的第一透镜组(11),当沿着光轴移动时呈现负折射力和倍率变化动作的第二透镜组(12) 固定到图像平面并具有正折射力的第三透镜组(13)和沿着光轴可移动的第四透镜组(14),以便保持像平面随着第二透镜组(12)的移动而移动 )和物体在参考平面的固定位置。 因此,通过将整个第三透镜组(13)垂直移动到光轴来校正由于相机抖动引起的图像的移动。 尺寸减小,像差小,因为光学性能结合的整个组都偏心。
