Abstract: A wide angle zoom lens includes sequentially from the object side, a first lens group having a negative refractive power overall and three lenses, including first to third lenses, having a negative refractive power and disposed farthest on the object side; a second lens group having a positive refractive power overall and one or more sets of cemented lenses; and a third lens group having a negative refractive power. This ultra wide angle zoom lens varies intervals between the first lens group, the second lens group, and the third lens group on the optical axis to zoom from the wide angle end to the telephoto end and satisfies given conditions to thereby enable a high zoom ratio, large diameter, and high resolution.

Abstract: The zoom lens comprises five or more groups of lens pieces, namely, the foremost or first lens group of positive refractive power located the closest to an object, the succeeding second lens group of negative refractive power, the third lens group of positive refractive power, the fourth lens group of positive refractive power, and the fifth lens group all arranged in this order, and if any, the rearmost lens group(s) closer to the imaging plane than the fifth lens group. The zoom lens meets requirements as defined in the conditional expression regarding a combined magnification of the fifth lens group and, if any, the rearmost lens group(s) closer to the imaging plane than the fifth lens group while the zoom lens is taking a telephoto position.

Abstract: A zoom lens includes sequentially from an object side a first lens group having a negative refractive power; a second lens group having a positive refractive power; a third lens group having a negative refractive power; and a fourth lens group having a negative refractive power. The first lens group, the second lens group, the third lens group, and the fourth lens group are moved along an optical axis to zoom from a wide angle end to telephoto end and such that an interval between the first lens group and the second lens group decreases and distances that the second lens group and the fourth lens group are moved are equivalent. The third lens group is moved along the optical axis, toward an image side to focus from a focused state at infinity to a focused state at a minimum object distance.

Abstract: A zoom lens exhibits a reduction in size, increased magnification, a reduction in variation of angle of view during zooming, and an increased focusing speed, said zoom lens being suitable for an imaging apparatus using a solid-state imaging device such as an interchangeable lens, a digital still camera, a digital video camera, or the like. The zoom lens has, in the lens system, at least: a first negative lens group having negative refractive power; a second negative lens group disposed further towards the image side than the first negative lens group, and which has negative refractive power; and a lens group (A) disposed so as to be adjacent to the image side of the second negative lens group. In the zoom lens, focusing from an infinite distance to a near object is performed by moving only the second negative lens group towards the image side, and prescribed conditions are satisfied.
