Abstract
A zoom lens system includes, in order from the object side to the image side, a first lens group having negative power and a second lens group having positive power. The first lens group includes at least two negative lenses. When zooming, one of the first lens group and the second lens group is fixed relative to the imaging surface, and the other moves along an optical axis to change an angle of view.
