zoom lens optical system

Although traditional mechanical zoom can change the magnification and adapt to changes in the shape of the actual size of the object, it demands very high in mechanical construction because mechanical optical zoom system lens group needs to be moved very precisely.

虽然传统的机械式变焦的方法能够改变放大率，适应实际物体的大小形状的变化，但是由于机械式光学变焦系统中各个透镜组的移动要非常精确，对机械构造的要求也就非常的高。
