    摘要: A zoom lens system includes a positive first lens group, a negative second lens group, and a positive rearward-remaining lens group. Upon zooming from the short to long focal length extremities, the distance between the first and second lens groups increases, the distance between the second and rearward-remaining lens groups decreases, and at least the first lens group and at least part of the rearward-remaining lens group moves. The second lens group includes a negative first sub-lens group which does not move during a focusing operation, and a negative second sub-lens group which moves in the optical axis direction during a focusing operation. The positive rearward-remaining lens group includes at least two lens groups, the distance therebetween mutually changing during zooming from the short focal length extremity to the long focal length extremity.

    摘要: A close-distance correcting lens system includes a positive first lens group and a negative second lens group, wherein traveling distances of the first lens group and the second lens group toward the object side differ from each other when carrying out a focusing operation on an object at infinity to an object at a close distance. The first lens group includes a positive first sub lens group, a negative second sub lens group, a diaphragm, and a positive third sub lens group, in that order from the object side. The second sub lens group includes an image-stabilizing lens group which is arranged to move in a direction orthogonal to the optical axis to change an imaging position of the object image to thereby correct any image shake of the object image.
