The first lens is a biconvex lens with positive refractive power. The second lens is a meniscus lens with negative refractive power and the convex surface of second lens faces the object side. The third lens is a meniscus lens with negative refractive power and the convex surface of third lens faces the object side. The fourth lens is a meniscus lens with positive refractive power and the concave surface of fourth lens faces the object side. The fifth lens is a biconcave lens with negative refractive power. The lens assembly satisfies the following condition: 1.10L1/DST<10.90, wherein DL1 is an effective diameter of the first lens and DST is an effective diameter of the stop.
