摘要： The disclosed zoom lens includes, from front to rear, a magnification-power variable lens assembly which serves for zooming and an image forming lens assembly which is stationary during zooming. The image forming assembly has a lens component B of negative refractive power which is preceded by at least one lens component A movable for focusing and which is followed by at least one lens component C movable for focusing. This structure makes achievement of a compact form and good stability in aberration correction possible throughout the entire focusing range.

摘要： A zoom lens system having, from front to rear, a positive first component, a negative second component, a positive third component and a fourth component, in which to effect zooming, the first, second and third components are moved axially in A relation such that the movements of the first and second components are non-linear with respect to that of the third component, and that when in the telephoto end, the first and third components lie more toward the front and the second component lies more toward the rear than when in the wide angle end. By specifying the relation in which the first, second and third components move as zooming nears the wide angle end, a valuable decrease in the diameter of the front lens members is achieved to provide a compact zoom lens system.
