Zoom lens and imaging apparatus

A zoom lens comprising, in order from an object side:

• a first lens group that has a positive refractive power and remains stationary with respect to an image plane during zooming;
• a plurality of movable lens groups that move by changing distances between groups adjacent to each other in a direction of an optical axis during zooming;
• and
• a final lens group that has a positive refractive power and remains stationary with respect to the image plane during zooming,
• wherein in the plurality of movable lens groups, at least one movable lens group has a negative refractive power,
• wherein the first lens group includes, in order from the object side, a first lens group front group that has a negative refractive power and remains stationary with respect to the image plane during focusing, a first lens group intermediate group that has a positive refractive power and moves in the direction of the optical axis during focusing, and a first lens group rear group that is set such that a distance in the direction of the optical axis between the first lens group rear group and the first lens group intermediate group changes during focusing and has a positive refractive power,
• wherein the first lens group front group has, successively in order from a position closest to the object side, a first negative lens which is a negative meniscus lens concave toward an image side, and a second negative lens which is a negative lens concave toward the object side, and
• wherein all Conditional Expressions (1) to (4) are satisfied,
• −0.5<DD12/f1a<−0.2 (1),
• 50<νn2<68 (2),
• 0.634<θgFn2+0.001625×νn2<0.675 (3), and
• 1<DDG1/f1<1.5 (4),
• where DD12 is a distance on the optical axis between the first negative lens and the second negative lens,
• f1a is a focal length of the first lens group front group,
• νn2 is an Abbe number of the second negative lens at the d line,
• θgFn2 is a partial dispersion ratio of the second negative lens between the g line and the F line,
• DDG1 is a distance on the optical axis from a lens surface closest to the object side in the first lens group to a lens surface closest to the image side in the first lens group in a state where an object at infinity is in focus, and
• f1 is a focal length of the first lens group in a state where the object at infinity is in focus.
