PROBLEM TO BE SOLVED: To provide a zoom lens having a small-sized entire system and a high zoom ratio and capable of obtaining high optical performance over an entire zooming range.SOLUTION: A zoom lens includes, in order from an object side to an image side, a positive first lens group, a negative second lens group, and two or more lens groups, is configured as a whole by a positive rear group in an entire zoom range, and changes a distance between adjacent lens groups when zooming. The second lens group has two or more negative lenses disposed in series in order from the object side to the image side. The negative lens disposed closest to the object side in the negative lenses disposed in series is represented by a negative lens G21, and the negative lens included in the negative lenses disposed in series and different from the negative lens G21 is represented by a negative lens G22.SELECTED DRAWING: Figure 1 |
