Zoom lens and imaging apparatus

A zoom lens consisting of, 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 in a direction of an optical axis between groups adjacent to each other during zooming;
• and
• a final lens group that has positive refractive power and remains stationary with respect to the image plane during zooming,
• wherein the first lens group consists of, 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 negative meniscus lens that is concave toward an image side, and a negative lens,
• wherein Conditional Expression (1) is satisfied,
• 1.84<Naven (1),
• where Naven is an average value of refractive indices of negative lenses in the first lens group front group at a d line.
