A zoom optical system (ZL) includes: a first lens group (G1) having negative refractive power; a second lens group (G2) having positive refractive power, the second lens group (G2) being disposed further toward an image than the first lens group (G1); and a succeeding lens group (GL) having a vibration-isolating group (GVRb) that moves so as to have a displacement component in a direction orthogonal to an optical axis, the succeeding lens group (GL) being disposed further toward the image than the second lens group (G2), a distance between the first lens group (G1) and the second lens group (G2) changing and a distance between the second lens group (G2) and the succeeding lens group (GL) changing upon zooming, and the following conditional expression being satisfied:

4.899|f1VRaw/fw|<1000.000

where f1VRaw is a composite focal length in a wide-angle end state of a lens disposed further toward the object than the vibration-isolating group, and fw is a focal length of the whole system in the wide-angle end state.

In an optical system, a height from an optical axis of a paraxial marginal ray that passes through a lens surface closest to an object is smaller than a maximum height from the optical axis of the paraxial marginal ray that passes through a lens surface on an image side of an intersection between the optical axis and a paraxial chief ray. The optical system includes an optical element disposed on an object side or the image side of the intersection. The optical element has positive refractive power in a case where the optical element is disposed on the object side of the intersection, and has negative refractive power in a case where the optical element is disposed placed on the image side of the intersection. A predetermined condition is satisfied.

A variable magnification optical system includes, in order from an object: a first lens group (G1) having a negative refractive power; a second lens group (G2); a third lens group (G3); a fourth lens group (G4) having a negative refractive power; and a fifth lens group (G5) having a positive refractive power, the system performing varying magnification by changing the distance between the first and second lens groups, the distance between the second and third lens groups, the distance between the third and fourth lens groups, and the distance between the fourth and fifth lens groups, and the fourth lens group including a 42nd lens group (G42) configured to be movable so as to have a component in a direction orthogonal to an optical axis and a 41st lens group (G41) disposed at an object-side of the 42nd lens group.

A zoom lens includes a plurality of lens units, in which a distance between adjacent lens units changes during zooming, a first aperture stop, and a second aperture stop disposed on an image side of the first aperture stop. An aperture diameter of the first aperture stop determines an F-number of the zoom lens at a wide-angle end. The plurality of lens units includes a negative lens unit having a negative refractive power that is disposed on the image side of the first aperture stop and on an object side of the second aperture. An aperture diameter of the second aperture stop changes during the zooming. The aperture diameter of the second aperture stop at the wide-angle end is larger than the aperture diameter of the second aperture stop at a telephoto end.

Provided is a zoom lens including a plurality of lens units, in which an interval between each pair of adjacent lens units is changed for zooming. The plurality of lens units consist of, in order from an object side to an image side: a first lens unit having a negative refractive power; a second lens unit having a positive refractive power; and a rear lens group including at least two lens units. The first lens unit and the second lens unit are configured to move during zooming.

A zoom lens consists of, in order from an object side, a negative first lens group, a positive second lens group, a positive third lens group, a negative fourth lens group, and a positive fifth lens group. The first lens group consists of, in order from the object side, a first A lens group that does not move during focusing, a first B lens group that moves during focusing, and a first C lens group that does not move during focusing. During zooming, the first lens group and the fifth lens group do not move, and the second lens group, the third lens group, and the fourth lens group move. The fourth lens group includes a stop.

A zoom lens includes, in order from an object side to an image side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and three or more lens units. A distance between adjacent lens units varies during zooming. A predetermined condition is satisfied.

A zoom lens includes, in order from the object side to the image side, a first lens unit having negative refractive power, a second lens unit having positive refractive power. A distance between adjacent lens units changes during zooming from a wide-angle end to a telephoto end. During zooming from the wide-angle end to the telephoto end, the first lens unit moves to the image side and then to the object side. The first lens unit includes four lenses or more, the four lenses or more including, in order from the object side to the image side, a first negative meniscus lens with a convex surface facing the object side and a second negative meniscus lens with a convex surface facing the object side. A predetermined condition is satisfied.

A zoom lens includes a negative first lens group, a positive second lens group, and a subsequent lens group in order from an object side. A focusing lens group closer to an image side than the first lens group moves during focusing. The first lens group consists of a first-a lens group and a first-b lens group in order from the object side. Assuming that an average of refractive indices of the negative lenses of the first-a lens group is Nd1ave, a focal length of the focusing lens group is ff, and a focal length of the first lens group is fl, Conditional Expression (1) of 1.73<Nd1ave <1.95 and Conditional Expression (2) of 1<|ff/f1|<3 are satisfied.
