Abstract: The zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a third lens group, a positive fourth lens group, and a positive fifth lens group. During zooming, the second lens group, the third lens group, and the fourth lens group move. The first lens group consists of, in order from an object side, a negative first a lens group, a positive first b lens group that moves during focusing, and a positive first c lens group. A most-image-side lens of the first b lens group is a negative meniscus lens having a convex surface facing an object side.

Abstract: The zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a third lens group, a positive fourth lens group, and a positive fifth lens group. During zooming, the second lens group, the third lens group, and the fourth lens group move. The fourth lens group includes a plurality of positive lenses and a negative lens disposed on a most-image-side. Assuming that an average value of Abbe numbers in positive lenses within the fourth lens group is vdp and an Abbe number of a negative lens disposed on a most-image-side of the fourth lens group is vdn, the zoom lens satisfies a conditional expression: 0

Abstract: The zoom lens consists of, in order from the object side, a positive first lens group that does not move during zooming, a negative second lens group that moves during zooming, a negative third lens group that moves during zooming, at least one lens group that moves during zooming, and a rear group that does not move during zooming. All distances between the lens groups adjacent to each other change during zooming. The zoom lens satisfies predetermined conditional expressions.

Abstract: A zoom lens consists of, in order from an object side, a positive first lens group, a negative second lens group, a positive third lens group, a positive fourth lens group, and a positive fifth lens group. During zooming from a wide angle end to a telephoto end, the first lens group is fixed relative to an image surface, and distances between the respective lens groups change in predetermined manners. The second lens group consists of predetermined four lens components.

Abstract: The zoom lens consists of, in order from an object side: a first lens group that remains stationary during zooming and has a positive refractive power; at least two movable lens groups that are moved during zooming; and a final lens group that remains stationary during zooming and has a positive refractive power. The final lens group consists of, in order from the object side, a front group and a rear group. The front group has, successively in order from a position closest to the object side, two or less positive lenses and one first front group negative lens, and a second front group negative lens that is different from the first front group negative lens at a position closest to an image side and is concave toward the image side. An aperture stop is provided between the movable lens group and the first front group negative lens. The rear group consists of a positive lens and a rear group negative meniscus lens that is convex toward the image side. In addition, the zoom lens satisfies predetermined conditional expressions.

Abstract: The zoom lens consists of, in order from an object side: a first lens group that has a positive refractive power; a second lens group that has a positive refractive power; a third lens group that has a negative refractive power; a fourth lens group that has a positive refractive power; and a fifth lens group that has a positive refractive power. The first lens group and the fifth lens group remain stationary with respect to an image plane during zooming. The second lens group, the third lens group, and the fourth lens group are moved by changing distances between the lens groups and adjacent groups in a direction of an optical axis during zooming, and are positioned to be closer to the image side at a telephoto end than at a wide-angle end. A stop is provided between the fourth lens group and the fifth lens group. In addition, Conditional Expression (1) is satisfied. 0.1
