Disclosed is a wide-angle zoom lens. The zoom lens comprises 2 lens array. The first lens array includes 6 lenses. The second lens array includes a meniscus lens and plural lenses having a negative refraction. The zoom lens satisfies the following three conditions. The first condition is 0.5 < f1/fN <0.82. Here, f1 is a focusing distance of the first lens array, and fN is a focusing distance on an angle edge. The second condition is 0.42 < f2/fN <0.82. Here, f2 is a focusing distance of the second lens array. The third condition is 1.3 < m2w < 1.9. Here, m2w is an imaging magnification of the second lens array on the angle edge. Thereby, the image angle, zoom ratio and focusing distance can be increased.
