Abstract
A zoom lens for use in endoscopic devices, in which a plurality of lens units is arranged in a lens cylinder perpendicular to the center line thereof. Among the plurality of lens units at least one lens unit may be hydraulically adjustable in the axial direction of the lens cylinder so as to vary the focal length of the zoom lens. Furthermore, the focal length of individual lenses of the lens unit may be varied by pneumatically varying the shape of the lenses in order to vary the total focal length of the zoom lens in this way.
