    • PROBLEM TO BE SOLVED: To provide a zoom lens that is suitable for a digital still camera, video camera, or the like, has a high variable power ratio despite its compact size, and has an image blur correction function.SOLUTION: The zoom lens entire system comprises, in order from an object side to an image side, a first lens group of positive refractive power, a second lens group of negative refractive power, a third lens group of positive refractive power, and a fourth lens group or the fourth lens group and a fifth lens group. Satisfactory optical performance in high variation can be obtained by changing the intervals between the lens groups. Further, the degree of freedom in aberration correction is increased by moving and displacing each lens group in the direction of an optical axis and changing and correcting a focal position so that air intervals between the lens groups are changed. Accordingly, while the satisfactory optical performance is maintained, a compact size in which the entire length and the diameter of a front lens are reduced can be achieved.
