The fourth lens group includes, sequentially from the object side, a first sub-lens group having a positive refractive power, a second sub-lens group having a negative refractive power, and a third sub-lens group. The second sub-lens group of the fourth lens group is moved along an optical axis to perform focusing.

摘要： A zoom lens with a wide angle of view and a high zooming ratio and a camera employing the zoom lens. The zoom lens includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, a fourth lens group having a negative refractive power, and a fifth lens group having a positive refractive power, wherein the first through fifth lens groups are sequentially arranged from an object side toward an image side. The first through fifth lens groups are moved during zooming between wide angle position to telephoto position in a manner that increases the distances between the first and second lens groups, between the third and fourth lens groups, and between the fourth and fifth lens groups and decreases a distance between the second and third lens groups. The zoom lens includes the five lens groups that are positive, negative, positive, negative, and positive, respectively, thus achieving a wide angle of view and a high zooming ratio.
