ABSTRACT:
A zoom lens has the capability to maintain image quality during image shifting for correcting for movement of the zoom lens. The zoom lens comprises, in order from the object side, a first lens group having positive refractive power, a second lens group having negative refractive power, a third lens group having negative refractive power, and a fourth lens group having positive refractive power. When changing magnification, the first lens group and the fourth lens group remain stationary along the optical axis and the second lens group and the third lens group move along the optical axis. The fourth lens group comprises, in order from the object side, a front lens group and a rear lens group. The front lens group of the fourth lens group moves in a direction substantially perpendicular to the optical axis to correct for movement of the image position caused by movement of the zoom lens.
