ABSTRACT:
A zoom lens system has, from the object side, a first lens unit and a second lens unit. The first lens unit has a negative optical power. The second lens unit has a positive optical power. The second lens unit includes front and rear lens units which each have a positive optical power. The front lens unit is shifted in a direction perpendicular to the optical axis to compensate for an image blurring. The zoom lens system fulfills the condition 0<.phi.2R/.phi.2F<1.0, where .phi.2R and .phi.2F represent optical powers of the rear and front lens units, respectively.
