A zoom lens for capturing images that enhances the image aberration correction rate to achieve high resolution and zooming ratio. The zoom lens includes, in sequence from an object side to an image side, a first lens group with positive refraction power, a second lens group with negative refraction power, a third lens group with positive refraction power, a fourth lens group with positive refraction power, a fifth lens group with positive refraction power and a sixth lens group with positive refraction power. The positions of first and sixth lens groups are fixed during photographing. When the zoom lens is made to zoom from a wide-angle end to a telephoto end thereof, the second lens group moves toward the image side while the fourth and fifth lens groups move toward the object side. In addition, the zoom lens has a reflection element so as to fold the image light entering thereof.
