摘要： A zoom lens system in which a movement locus of a focusing lens unit is defined by synthesizing a focus cam and a zoom compensation cam so as to achieve an in-focus state by a substantially constant amount of rotation for an identical object distance independently of a zooming state. In zooming, an amount of movement of the focusing lens unit is defined by a combination of the focus cam and the zoom compensation cam. An amount of movement of a non-focusing lens unit is defined by a combination of a zoom cam and the zoom compensation cam. In focusing, the amount of movement of the focusing lens unit is defined by the focus cam. The zoom lens system satisfies specified formulas so that the number of data of specific coefficients required for auto-focusing can be reduced, and an error upon calculation of the lens driving amount of the focusing lens unit using stored specific coefficients in correspondence with a detected defocus amount can be reduced.

摘要： A zoom lens includes a plurality of lens units movable along the optic axis, and a mechanism for prescribing the movements of the plurality of lens units along the optic axis and making the focal length of the zoom lens adjustable within a desired range. At least one of the plurality of lens units is moved along the optic axis to form the image of an obect lying at any distance from the zoom lens on a predetermined surface. The mechanism has a member formed with at least one slot which prescribes the movement of the at least one lens unit along the optic axis. The at least one lens unit is moved in accordance with the at least one slot both when it is moved along the optic axis to change the focal length of the zoom lens and when it is moved along the optic axis to form the image of the object on the predetermined surface.

摘要： A zoom lens having a change-magnification range ranging from wide angle to telephoto comprises, in succession from the object side, first lens group of positive refractive power movable on the optical axis, a second lens group of negative refractive power fixed relative to the image plane at a determined position, a third lens group of negative refractive power movable on the optical axis, and a fourth lens group of positive refractive power movable on the optical axis. The first and fourth lens groups are moved toward the object side in linear fashion to change magnification from the wide angle end to the telephoto end while the third lens group is moved toward the object side at the same time in non-linear fashion to keep the image plane at the determined position.

摘要： A zoom lens barrel has a lens unit with both functions of zooming and focusing, comprises a first cyindrical member having a zoom guide groove (or zoom cam) corresponding to a zooming orbit of displacement of the lens unit with both the functions of zooming and focusing and a second cylindrical member having a focus guide groove (or focus cam) for displacing the lens unit with the functions of zooming and focusing along an optical axis for focusing. The focus guide groove or focus cam is non-linear and has an area inclined with respect to the optical axis to permit the relative displacement of the first and second cylindrical members to each other in the optical axis direction necessary for the focusing of a given object to be held substantially constant irrespective of the status of zooming and also permit the displacement of the lens unit with both the functions of zooming and focusing for focusing to be varied according to the status of zooming.
