COMPACT AND HIGH VARIABLE POWER ZOOM LENS

摘要

PROBLEM TO BE SOLVED: To provide a compact and high variable power zoom lens capable of having 75 degrees or more of the angle of view at a wide-angle end, while having a zoom magnification of twelve times or more and ensuring miniaturization.;SOLUTION: A zoom lens comprises in order from an object side: a first lens group G1 having positive refractive power; a second lens group G2 having negative refractive power; a third lens group G3 having positive refractive power; and a subsequent rear group including one or more lens groups. The zoom lens moves individual lens groups to perform variable power and satisfies predetermined conditions of the angle of view at a wide-angle end, focal point distances of the lens groups, and the thickness of the first lens group.;COPYRIGHT: (C)2015,JPO&INPIT
