Abstract

A lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, all of which are arranged in order from an object side to an image side along an optical axis. The first lens is with positive refractive power and includes a convex surface facing the object side. The second lens is with negative refractive power and includes a concave surface facing the image side. The third lens is with refractive power and includes a convex surface facing the image side. The fourth, fifth, and sixth lenses are with refractive power. The lens assembly satisfies: 2 mm<f+f<35 mm, wherein fis an effective focal length of the fifth lens and fis an effective focal length of the sixth lens.
