ABSTRACT:
A zoom lens system comprises, in the following order from the object side, a first lens group with a negative refractive power and a second lens group with a positive refractive power. When changing the focal length, the distance of an air space between the first lens group and the second lens group is changed. The second lens group has a front group with a positive refractive power and a rear group with a negative refractive power. An image position is changed by shifting at least one lens element of the front group of the second lens group along a direction transverse to the optical axis.
