Zoom lens

A zoom lens includes a first lens group, a second lens group, a third lens group, a fourth lens group, a fifth lens group and a sixth lens group all of which are along optical axis and are arranged in sequence from an object side to an image side. The first lens group is with positive refractive power. The second lens group is with negative refractive power. The third lens group is with positive refractive power. The fourth lens group is with negative refractive power. The fifth lens group is with positive refractive power. The zoom lens satisfies the following condition: |fw/f6| < 0.15, wherein fw is the effective focal length of the zoom lens that operates in the wide-angle mode and f6 is the effective focal length of the sixth lens group. When the zoom lens operates from wide-angle mode to telephoto mode, a distance between the first lens group and the second lens group increases, a distance between the second lens group and the third lens group decreases, a distance between the third lens group and the fo
