Abstract: A zoom lens includes a positive first lens group, a negative second lens group, a positive third lens group, and a subsequent group consisting of plural lens groups in order from an object side. In a case of zooming, an interval with an adjacent lens group is changed. The third lens group includes two uncemented positive lenses consecutively arranged in order from a side closest to the object side to an image side. A lens group closest to the image side in the subsequent group consists of a negative meniscus lens having a concave surface toward the object side and a positive lens having a convex surface toward the object side in order from the object side to the image side.

Abstract: The imaging lens consists of, in order from an object side, a first lens group having a negative refractive power, a second lens group having a positive refractive power, and a third lens group having a negative refractive power, and is configured such that, during focusing, the first lens group and the third lens group remain stationary with respect to an image plane, the second lens group moves in the direction of an optical axis, the first lens group includes a first-a negative lens and a first-b negative lens successively in order from a position closest to the object side, and that the second lens group includes an aperture stop that moves integrally with the second lens group during focusing.

Abstract: The zoom lens includes a positive first lens group, a negative second lens group, a positive third lens group, a negative fourth lens group, a negative fifth lens group, and a positive sixth lens group in order from an object side. All distances between adjacent lens groups change during zooming. The first lens group consists of a negative lens, a positive lens, and a positive lens in order from the object side. Only the fourth lens group moves to an image side during focusing from a long range to a short range. Conditional Expression related to a distance from a lens surface of the first lens group closest to the object side to an image plane and a distance from a lens surface of the second lens group closest to the object side to the image plane is satisfied.

Abstract: A zoom lens is constituted by, in order from the object side: a positive first lens group; a negative second lens group; a positive third lens group; a positive fourth lens group; a negative fifth lens group, and a positive sixth lens group. The distances among adjacent lens groups change when changing magnification from the wide angle end to the telephoto end. The first lens group is constituted by, in order from the object side, a negative lens, a positive lens, and a positive lens. The third lens group has a positive lens at the most object side thereof. A predetermined conditional formula is satisfied.

Abstract: A wide angle lens is constituted by, in order from the object side to the image side: a front group having a negative refractive power; an aperture stop; and a rear group having a positive refractive power. The front group includes, in order from the object side to the image side, a first meniscus lens having a negative refractive power, and a second meniscus lens having a negative refractive power. The rear group includes a first cemented lens formed by cementing a negative lens and a positive lens, provided in this order from the object side, together, most toward the image side, and a lens having at least one aspherical surface and a negative refractive power provided adjacent to the first cemented lens at the object side thereof.

Abstract: The imaging lens consists of, in order from the object side, a first lens group having a positive refractive power, a stop, a second lens group having a positive refractive power, and a third lens group. The third lens group includes one or more positive lenses and one or more negative lenses. During focusing, an entirety of the first lens group, the stop, and the second lens group, or an entirety of the second lens group integrally moves as a focus group, and the third lens group remains stationary with respect to an image plane. The imaging lens satisfies predetermined conditional expressions.

Abstract: The imaging lens consists of, in order from an object side: a first lens group G1; a diaphragm; and a second lens group G2 that has a positive refractive power. The first lens group G1 consists of, in order from the object side, a first A lens group G1A that consists of two negative meniscus lenses concave toward an image side, and a first B lens group G1B that consists of only one positive lens or a negative lens and a positive lens. The second lens group G2 consists of, in order from the object side, a biconvex lens, a biconcave lens, one or two biconvex lenses, and a negative meniscus lens that is concave toward the object side. With such a configuration, the imaging lens satisfies predetermined conditional expressions.
