By controlling the ratio of the focal length of the second lens group and the focal length of the tele-photo end, image distortion may be controlled, and the total length of the lens may be reduced to shrink the size of the lens. Hence production costs may be reduced, which is important to mass production.

From the object plane to the image plane, the first lens group has a negative refractive power, the second lens group has a positive refractive power, and the third lens group has a positive refractive power. As the focal length of the zoom lens changes from long (telescope) to short (wide-angle), the second lens group moves from the object plane to the image plane. The third lens group and the first lens group move with the second lens group.
