Abstract
A zoom lens system comprising: a first lens unit having positive optical power; a second lens unit having positive optical power; and at least one subsequent lens unit, wherein the zoom lens system has an image blur compensating lens unit which moves in a direction perpendicular to an optical axis, at least the first lens unit moves along the optical axis at the time of zooming from a wide-angle limit to a telephoto limit, the second lens unit or a third lens unit which is located closest to the object side in the at least one subsequent lens unit moves along the optical axis at the time of focusing from an infinity in-focus condition to a close-object in-focus condition, and the condition: 0.10<|m|/(f−f)<0.40 (m: the maximum value among the amounts of movement of each subsequent lens unit at the time of zooming from a wide-angle limit to a telephoto limit, f, f: focal lengths of the entire system at a telephoto limit, at a wide-angle limit) is satisfied; an interchangeable lens apparatus; and a camera system are provided.
