摘要： A zoom lens system, with both zooming and focusing functions, has a plurality of lens groups including at least two focusing lens groups which move differently from each other either in zooming or in focusing, wherein when a certain movement trace for zooming is expressed with a variable of rotation angle of a rotating barrel for defining a displacement amount of a lens group along an optical axis, a movement trace of the first focusing lens group is formed by a combination of a first focus cam with a first compensating zoom cam, a movement trace of an n-th focusing lens group is formed by a combination of an n-th focus cam with an n-th compensating zoom cam, and a movement trace of each movable non-focusing lens group taking no part in focusing is formed by a combination of one of the first to n-th compensating zoom cams with a zoom cam for the non-focusing lens group.
