ABSTRACT:
A zoom lens system with a function of reducing image vibration is constituted of, in the order from an object side, a first lens group having a positive refracting power; a second lens group being provided so as to be shiftable substantially in a direction perpendicular to an optical axis and having a negative refracting power; and a third lens group having a positive refracting power. When varying the focal length of the zoom lens system from wide angle end to telephoto end, the first and third lens groups are moved on the optical axis toward the object side. The zoom lens system further has a vibration detecting device for detecting vibration of the zoom lens system; a drive device for driving the second lens group; and a control device for controlling the drive device based on the output of the vibration detecting device.
