Zoom lens and imaging apparatus

A zoom lens consisting of, in order from an object side to an image side:

• a first lens group that has a positive refractive power;
• a second lens group that has a negative refractive power;
• and
• a subsequent group that has a plurality of lens groups, wherein:
• the zoom lens includes an aperture stop at a position closer to the image side than a lens surface closest to the image side in the second lens group,
• a lens group closest to the image side in the subsequent group includes at least one negative lens of which an object side lens surface is a concave surface being in contact with air,
• during zooming, a spacing between the first lens group and the second lens group changes, a spacing between the second lens group and the subsequent group changes, and spacings between all adjacent lens groups in the subsequent group change,
• during zooming, lens spacings inside the first lens group, the second lens group, and the plurality of lens groups in the subsequent group are unchanged,
• the first lens group consists of, in order from the object side to the image side, a cemented lens formed by a negative meniscus lens having a convex surface facing toward the object side and a positive lens cemented together, and a positive meniscus lens having a convex surface facing toward the object side,
• an uncemented negative meniscus lens having a convex surface facing toward the image side is arranged closest to the image side of the second lens group,
• the subsequent group includes, continuously in order from a position closest to the object side to the image side, a third lens group that has a positive refractive power, and a fourth lens group that has a positive refractive power,
• the lens group closest to the image side in the subsequent group has a negative refractive power,
• the subsequent group includes only three cemented lenses, each formed by a positive lens and a negative lens cemented together,
• the subsequent group includes a focus group that moves along an optical axis during focusing at a position closer to the image side than the fourth lens group, and in a case in which
• an Abbe number of a lens closest to the object side in the first lens group based on a d line is v1,
• a focal length of a lens group closest to the object side among lens groups that have positive refractive powers and that are included in the subsequent group in a state in which an infinite distance object is in focus is fp,
• a focal length of the second lens group is f2, and
• a focal length of the first lens group is f1,
