摘要： A zoom lens including, from front to rear, a first lens group of positive power, a second lens group of negative power, a third lens group of positive power, a fourth lens group of negative power, and a fifth lens group of positive power. For zooming from the shortest focal length to the longest focal length, the first lens group is moved forward, the air space between the first and second lens groups is increased, the air space between the second and the third lens groups is decreased, the air space between the third and fourth lens groups is increased, and the air space between the fourth and fifth lens groups is decreased. The fifth lens group remains stationary during zooming. This construction and arrangement results in a zoom lens of compact form with a large aperture while still permitting good stability of aberration correction throughout a greatly extended zooming 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.
