Abstract:
A zoom lens system according to an example embodiment includes, sequentially from an object side to an image plane side along an optical axis, a first lens group having a negative refractive power and including at least one doublet lens, the doublet lens including two lenses, a second lens group having a positive refractive power, and a third lens group having a positive refractive power, wherein the first lens group and the second lens group are configured to move along the optical axis to perform zooming and focusing, and the zoom lens system satisfies 3.0<Vdf/Vdr<6.0, where Vdf denotes an Abbe number of a lens arranged at the object side in a doublet lens, and Vdr denotes an Abbe number of a lens arranged at the image plane side in a doublet lens.

Claim (Index 5):
The zoom lens system of  claim 4 , wherein the sixth lens and the tenth lens each comprise an aspherical surface, respectively, and\n wherein\n Vd 6>40, and \n Vd 10>70, \n where Vd6 and Vd10 respectively denote Abbe numbers of the sixth lens and the tenth lens.
