Abstract
A lens assembly includes a first lens group, a second lens group, a third lens group, a fourth lens group, and a reflective element. The first lens group is with refractive power. The second lens group is with positive refractive power. The third lens group is with positive refractive power. The fourth lens group is with refractive power. The reflective element includes a reflective surface. A light from an object sequentially passes through the first lens group, the second lens group, the third lens group, and the fourth lens group to an image side along an axis. The reflective element is disposed between an object side and the image side along the axis. Intervals of the lens groups are changeable when the lens assembly zooms from a wide-angle end to a telephoto end.
