Zusammenfassung:Provided is a zoom lens. The zoom lens includes a first lens group (G1) with a positive refractive power, a second lens group (G2) with a negative refractive power, a third lens group (G3) with a positive refractive power, a fourth lens group (G4) with a negative refractive power, and a fifth lens group (G5) with a positive refractive power. The first through fifth lens groups are sequentially arranged toward an image side from an object side, and the second, fourth, and fifth lens groups move long the optical axis during zooming.
