Abstract: The zoom lens consists of, in order from the object side, a first lens group that has a positive refractive power, a second lens group that has a positive refractive power, and a subsequent group. During zooming, a spacing between the first lens group and the second lens group changes, and a spacing between the second lens group and the subsequent group changes. The subsequent groups include a focusing group that moves during focusing.

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 second lens group has a negative lens and a cemented lens successively in order from a most object side to an image side. The cemented lens of the second lens group has a first negative lens and a first positive lens successively in order from an object side to an image side. A predetermined conditional expression for the first positive lens is satisfied.

Abstract: A zoom lens has, in order from an object side, a focusing unit including a focusing lens group moving for focusing, a variable magnification unit including at least two variable magnification lens groups moving while changing a mutual interval for variable magnification, an aperture stop, and an image forming unit including an image forming lens group. The image forming unit consists of, in order from the object side, an M1 lens group, an M2N lens group, and an M3 lens group. The M2N lens group is replaceable with an M2E lens group that enlarges an image forming magnification. The M2E lens group satisfies predetermined conditional expressions (1) to (4).

Abstract: A zoom lens consists of a positive first lens group that is fixed during zooming, a negative second lens group that moves during zooming, a positive third lens group that moves during zooming, a positive fourth lens group that moves during zooming, and a positive fifth lens group that is fixed during zooming. During zooming from a wide angle end to a telephoto end, the fourth lens group moves from an image side to an object side, the second lens group and a composite group consisting of the third lens group and the fourth lens group pass through points where respective lateral magnifications are −1 at the same time, the fifth lens group consists of a negative fifth A lens group that moves during anti-shake operation, and a positive fifth B lens group that is fixed during the anti-shake operation, and the lateral magnification of the fifth A lens group is negative.

Abstract: A zoom lens consists of, in order from an object side, a positive first lens group fixed relative to the image surface during zooming, at least two movable lens groups including a negative second lens group being adjacent to the first lens group, the at least two movable lens groups being movable by changing a distance in an optical-axis direction to an adjacent group during zooming; and a final lens group arranged on the most image side and fixed relative to the image surface during zooming. The first lens group has, continuously in order from the most object side, a first negative lens having a concave surface facing an image side, a second negative lens, and a third positive lens. A predetermined conditional expression relating to the first lens group is satisfied.

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 plurality of movable lens groups that move during zooming, and a final lens group that has a positive refractive power and remains stationary during zooming. The final lens group has two or more positive ED lenses formed of a material satisfying predetermined conditional expressions. The predetermined conditional expressions, which relate to extraordinary low dispersion and temperature coefficients of the refractive indices of the positive lenses in the movable lens group closest to the image side and the final lens group, are satisfied.
