Present embodiments provide for an optical lens assembly. The optical lens assembly includes a first lens element, a second lens element, a third lens element, a fourth lens element, and a fifth lens element positioned sequentially from an object side to an image side. Through arrangement of convex or concave surfaces of the five lens elements, the length of the optical lens assembly may be shortened while providing better optical characteristics and imaging quality.
