Abstract:
1. A zoom lens comprising in order from an object side to an image side where N represents an integer equal to 5 or 7: a first lens unit having a positive refractive power; a second lens unit having a negative refractive power; an (N−2)-th lens unit having a positive refractive power; an (N−1)-th lens unit having a negative refractive power; and an N-th lens unit having a positive refractive power, wherein distances between adjacent ones of the first, second, (N−2)-th, (N−1)-th and N-th lens units in a direction of an optical axis are changed during zooming, wherein the (N−1)-th lens unit includes an image stabilizing unit movable for image blur correction in a direction including a directional component orthogonal to the optical axis, and wherein the following conditions are satisfied: where BldN represents a thickness of the N-th lens unit on the optical axis, TDw represents a distance on the optical axis between a most object side lens surface and a most-image side lens surface at a wide-angle end, fw represents a focal length of the entire zoom lens at the wide-angle end, and f
