<P>PROBLEM TO BE SOLVED: To provide a zoom lens system having a high resolution, being adaptable for wide-angle photography with a field angle of 72° or more at a wide angel end regardless of a small size, and having a large zoom ratio of three times or more; an imaging device including the zoom lens system; and a compact camera equipped with the imaging device. <P>SOLUTION: A zoom lens system has a plurality of lens groups configured with at least one lens element; is composed of a first lens group having negative power and at least one subsequent lens group in order from an object side to an image side; and is equipped with a retractable lens group which changes an interval between the first lens group and the subsequent lens group when zooming from a wide angle end to a telephoto end during imaging, and during collapsing, retracts along an axis different from an axis during imaging, and an image blurring correction lens group which moves in a vertical direction to an optical axis for optically correcting an image blurring. The retractable lens group is a different lens group from the image blurring correction lens group. The zoom lens system, an imaging device, and a camera are provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
