摘要：
A wide-angle zoom lens system includes a first lens group with negative refraction power, a second lens group with positive refraction power, and a third lens group with positive refraction power. The first lens group, the second lens group, and the third lens group move along an optical axis of the zoom lens system in focusing. The wide-angle zoom lens system satisfies the formulas: 0.77
