<p>PROBLEM TO BE SOLVED: To obtain a zoom lens which has a high zoom ratio, is miniaturized in an optical axis direction, and has high optical performance in the entire zoom area.SOLUTION: The zoom lens comprises, in order from an object side to an image side, a first lens group having positive refractive power, a second lens group having negative refractive power, a third lens group having positive refractive power, and a rear group including one or more lens groups. In zooming, an interval between adjacent lens groups is changed and the second lens group and the third lens group include a resin lens. The focal length f2p of the resin lens included in the second lens group, the focal length f3p of the resin lens included in the third lens group, and the focal length ft of the entire system at a telephoto end are properly set respectively.</p> |
