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 15):
The zoom lens system of  claim 14 , wherein the five lenses included in the second lens group comprise:\n a sixth lens having a positive refractive power; a seventh lens having a positive refractive power; an eighth lens having a negative refractive power; a ninth lens having a positive refractive power; and a tenth lens having a negative refractive power.
