A zoom lens including a first lens group with a negative refractive power and a second lens group with a positive refractive power is provided. The first lens group is composed of a first lens, a second lens, and a third lens. Refractive powers of the first lens, the second lens, and the third lens are respectively negative, negative, and positive. Moreover, the second lens group is disposed between the first lens group and an image side. The second lens group is composed of a fourth lens, a fifth lens, and a sixth lens. Refractive powers of the fourth lens, the fifth lens, and the sixth lens are respectively positive, negative, and positive. The first lens group and the second lens group are capable of moving between an object side and the image side. The zoom lens has advantages of wide angle and small volume.
