A lens assembly includes a first lens group, a second lens group, a third lens group, a fourth lens group, and a fifth lens group, all of which are arranged in order from a first side to a second side along an axis. The first lens group is with negative refractive power. The second lens group is with positive refractive power. The third lens group is with refractive power. The fourth lens group is with refractive power. The fifth lens group is with refractive power. The lens assembly further includes a first reflective element disposed between the first lens group and the fifth lens group, wherein the first reflective element includes a first reflective surface.

Lens assembly

A lens assembly includes a first lens, a second lens, a third lens, and a fourth lens. The first lens is with positive refractive power and includes a concave surface facing an object side and a convex surface facing an image side. The second lens is with negative refractive power and includes a concave surface facing the object side. The third lens is with positive refractive power. The fourth lens is with refractive power and includes a concave surface facing the image side. The first lens, the second lens, the third lens, and the fourth lens are arranged in order from the object side to the image side along an optical axis. The lens assembly satisfies: TTL/f&#x3e;1.2; wherein TTL is a total length of optical system of the lens assembly and f is an effective focal length of the lens assembly.
