摘要：
A lens assembly includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The first lens is with positive refractive power and includes a convex surface facing an object side and a concave surface facing an image side. The second lens is with positive refractive power. The third lens is with negative refractive power and includes a convex surface facing the object side. The fourth lens is with negative refractive power and includes a concave surface facing the object side. The fifth lens is with positive refractive power and includes a convex surface facing the image side.
