摘要:
An object is to reduce the effect of defocusing due to the movement of an image plane when a shifting lens group movable in a direction perpendicular to the optical axis for correcting hand jiggling is positionally deviated along the optical axis, thereby maintaining high optical performance at the time of correcting hand jiggling. A zoom lens 1 includes a plurality of lens groups with distances between the lens groups being changed for variable power. A final lens group L5 which is positioned most closely to an image side has a sub lens group GS (G8) having a positive refractive power and a sub lens group GR (G9) disposed adjacent to the sub lens group GS (G8) on the image side and having a positive refractive power. The sub lens group GS is shiftable in a direction perpendicular to the optical axis for correcting image blurs. The sub lens group GS has a lateral magnification βs and the sub lens group GR has a lateral magnification βR, the lateral magnifications satisfying the following conditional expressions (1), (2): βs
