Abstract: The present invention is directed to an imaging lens with an optical system that comprises the foremost lens group closest to an object and of positive refractivity, the succeeding middle lens group, and the rearmost lens group closest to an image plane and of negative refractivity where the middle lens group, having the first, second, and third lens subgroups disposed in series, is moved axially along the optical axis for focusing, and the foremost lens group includes at least three or more convex lens pieces and a single concave lens piece and meets predetermined requirements defined in formulae. The imaging lens has a quality image stabilizing system in which a light-weight lens piece(s) is moved in directions perpendicular to the optical axis.

Abstract: A high-power zoom lens that achieves size and price reduction, and at the same time provides high-quality imaging. This lens includes at least four lens groups arranged along an optical axis, which are moveable along the axis in order to achieve changes in magnification. The first, third, and fourth lens groups have positive refractive powers, and the second group has a negative refractive power. The second lens group includes a negative meniscus lens arranged closest to the object, provided with a convex surface at the object side. A negative lens is arranged next to the negative meniscus lens, and a negative lens provided with a concave surface at the object side is arranged closest to the image. The fourth lens group includes at least two positive lenses and one negative lens.
