Abstract: A zoom lens includes a positive first lens group, a negative second lens group, a positive third lens group, a positive fourth lens group, and a fifth lens group 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 positive lenses consecutively arranged in order from a side closest to the object side to an image side. The fifth lens 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 zoom lens consists of, in order from the object side, a first lens group that has a positive refractive power and remains stationary during zooming, a second lens group that moves during zooming, and a subsequent lens group. The first lens group has a negative lens at a position closest to the object side. The subsequent lens group has, successively in order from a position closest to the image side, a final positive lens group that remains stationary during zooming, a positive lens group that moves during zooming, a stop, and a negative lens group that moves during zooming. The stop moves integrally with the positive lens group during zooming. The stop first moves to the object side, and reversely moves during zooming from the wide-angle end to the telephoto end. Predetermined conditional expressions are satisfied.

Abstract: An imaging lens is constituted by, in order from the object side to the image side: a first lens group; a stop; and a second lens group having a positive refractive power. The first lens group is constituted by, in order from the object side to the image side: a 1-1 negative meniscus lens having a concave surface toward the image side; a 1-2 negative meniscus lens having a concave surface toward the image side; a 1-3 biconcave lens; and a 1-4 positive lens. The second lens group is constituted by, in order from the object side to the image side: a 2A lens group having a positive refractive power; and a 2B lens group having a positive refractive power as a whole, constituted by a 2B-1 positive lens, a 2B-2 negative lens, and a 2B-3 positive lens.

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 second lens group has a negative 2R lens group constituted by a cemented lens formed by cementing a negative lens and a positive lens, provided in this order from the object side, together, and a negative single lens. The fifth lens group is constituted by, in order from the object side, a negative lens, a negative lens, and a positive lens.

Abstract: A zoom lens consists of a negative first lens group, a positive second lens group, and a positive third lens group. Upon zooming from the wide angle end to the telephoto end, the first, second, and third lens groups are moved such that distance between the first lens group and the second lens group is reduced, and distance between the second lens group and the third lens group is increased. The first lens group is composed of a negative lens and a positive lens from the object side. The zoom lens satisfies given conditional expressions related to radius of curvature, center thickness, refractive index, and Abbe number of the negative lens and refractive index of the positive lens of the first lens group, and distance from the most object side surface to the most image side surface of the first lens group on the optical axis.
