A compact zoom lens system includes, when viewed from an object side, a first lens group with positive refractive power and a second lens group. The magnification of the system can be changed by varying a distance between the first lens group and the second lens group, wherein the following condition is satisfied: Lt/ft<0.78 wherein: Lt is the distance between the surface of lens closest to the object and the image plane; and ft is the focal length of the zoom lens system.
