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;
• a third lens group that has a negative refractive power;
• and
• a fourth lens group that has a positive refractive power,
• wherein the fourth lens group includes only five lens groups, as lens groups, which consists of, in order from the object side to the image side, a fourth A lens group which has a positive refractive power, a fourth B lens group which has a negative refractive power and moves in a direction intersecting with an optical axis during image blur correction, a fourth C lens group which has a positive refractive power, a fourth D lens group which moves along the optical axis during focusing, and a fourth E lens group which has a refractive power with a sign different from that of a refractive power of the fourth D lens group,
• a stop is disposed on the image side from a surface closest to the image side in the third lens group,
• during zooming from a wide-angle end to a telephoto end, the second lens group moves to the image side, the third lens group moves to the image side after moving to the object side, and the first lens group, the stop, the fourth A lens group, the fourth B lens group, the fourth C lens group, and the fourth E lens group remain stationary with respect to an image plane,
• during image blur correction, the fourth A lens group and the fourth C lens group remain stationary with respect to the image plane,
• during focusing, the lens groups other than the fourth D lens group remain stationary with respect to the image plane, and
• assuming that
• a composite focal length of the fourth A lens group, the fourth B lens group, and the fourth C lens group is f4ABC, and
• a focal length of the fourth D lens group is f4D,
• Conditional Expression (1) is satisfied, which is represented by
• 0.5<f4ABC/|f4D|<3 (1).
