    • An enhanced variable power zoom lens is lightweight in whole and in part, especially, having its focusing lens optics reduced in weight so as to relieve of a load on a focusing drive system, and having its anti-vibration lens optics reduced in both diameter and weight so as to relieve of a load on an anti-vibration drive system and downsize the same. The zoom lens has the foremost or first lens group of positive refractivity, the second lens group of negative refractivity, the third lens group of positive refractivity, the fourth lens group of negative refractivity, and the fifth lens group arranged in sequence from a position closer to the object. The fourth lens group moves toward the image plane for focusing on from the infinity to a proximity object while part of the third lens group moves orthogonal to the optical axis for shifting an image.
    • 增强型可变功率变焦透镜的整体和部分重量轻,特别是其聚焦透镜光学元件的重量减轻,以减轻聚焦驱动系统上的负载,并使其防振透镜光学器件的直径和直径都减小 以减轻抗振动驱动系统的负载并使其小型化。 变焦透镜具有正折射率的第一或第一透镜组,负折射率的第二透镜组,正折射率的第三透镜组,负折射率的第四透镜组,以及从靠近的位置排列的第五透镜组 对象。 第四透镜组朝着图像平面移动,用于从无限远到近距离物体聚焦,而第三透镜组的一部分正交于光轴移动以移动图像。
