A zoom lens comprising, in order from an object side to an image side, a first lens unit having a negative refractive power, and a rear unit having a positive refractive power as a whole and including all lens units (L2,..., LN) of the zoom lens on the image side of the first lens unit, wherein a distance between the first lens unit and the rear unit is changed during zooming, wherein the rear unit includes a subunit that is moved in a direction having a component of a direction orthogonal to an optical axis during image stabilization, wherein the first lens unit includes, in order from the object side to the image side, three or more negative lenses, and wherein the following inequalities are satisfied: − 20 % < Dist_w < − 8 % − 0.4 < f 1 / fLN < 0.7 Dist_w % = yp − y / y × 100 where Dist_w is a distortion amount at a maximum image height in an in-focus state at infinity at a wide-angle end, f1 is a focal length of the first lens unit, fLN is a focal length of a final lens unit which is arranged closest to an image side among the lens units included in the rear unit, y is an ideal image height in a central projection method, and yp is a real image height; wherein herein the term lens unit denotes, for the first lens unit and the lens units included in the rear unit, a group of lenses that move or stand still integrally during zooming, or a single lens that moves or stands still during zooming; wherein the zoom lens further comprises an aperture stop provided on the object side of or inside of a second lens unit which is arranged closest to the object side among the lens units included in the rear unit; wherein the rear unit includes two or more lens units disposed on the image side of the subunit a distance between which changes during zooming; and wherein the rear unit includes a focus unit disposed on the image side of the subunit which is configured to move during focusing; characterized in that the following inequality is satisfied: − 2.2 < f 1 / skw < − 0.9 where skw is a backfocus of the zoom lens at the wide-angle end. wherein a distance between the first lens unit and the rear unit is changed during zooming, wherein the rear unit includes a subunit that is moved in a direction having a component of a direction orthogonal to an optical axis during image stabilization, wherein the first lens unit includes, in order from the object side to the image side, three or more negative lenses, and wherein the following inequalities are satisfied: − 20 % < Dist_w < − 8 % − 0.4 < f 1 / fLN < 0.7 Dist_w % = yp − y / y × 100 where Dist_w is a distortion amount at a maximum image height in an in-focus state at infinity at a wide-angle end, f1 is a focal length of the first lens unit, fLN is a focal length of a final lens unit which is arranged closest to an image side among the lens units included in the rear unit, y is an ideal image height in a central projection method, and yp is a real image height; wherein herein the term lens unit denotes, for the first lens unit and the lens units included in the rear unit, a group of lenses that move or stand still integrally during zooming, or a single lens that moves or stands still during zooming; wherein the zoom lens further comprises an aperture stop provided on the object side of or inside of a second lens unit which is arranged closest to the object side among the lens units included in the rear unit; wherein the rear unit includes two or more lens units disposed on the image side of the subunit a distance between which changes during zooming; and wherein the rear unit includes a focus unit disposed on the image side of the subunit which is configured to move during focusing; characterized in that the following inequality is satisfied: − 2.2 < f 1 / skw < − 0.9 wherein herein the term lens unit denotes, for the first lens unit and the lens units included in the rear unit, a group of lenses that move or stand still integrally during zooming, or a single lens that moves or stands still during zooming; wherein the zoom lens further comprises an aperture stop provided on the object side of or inside of a second lens unit which is arranged closest to the object side among the lens units included in the rear unit; wherein the rear unit includes two or more lens units disposed on the image side of the subunit a distance between which changes during zooming; and wherein the rear unit includes a focus unit disposed on the image side of the subunit which is configured to move during focusing; characterized in that the following inequality is satisfied: − 2.2 < f 1 / skw < − 0.9 where skw is a backfocus of the zoom lens at the wide-angle end.
