摘要： A zoom lens system comprises, in order from an object side, a positive first lens unit including a reflective optical element, a negative second lens unit, a positive third lens unit and a positive fourth lens unit, or a positive first lens unit, a negative second lens unit, a positive third lens unit, a negative fourth lens unit and a positive fifth lens unit. During zooming from a wide-angle end toward a telephoto end, the first lens unit is fixed, at least the second and third lens units move, and a space between the lens units changes. The second lens unit is positioned closer to an image-surface side in the telephoto end than in the wide-angle end, and the third lens unit is positioned closer to the object side in the telephoto end than in the wide-angle end. An image taking apparatus including the zoom lens system is also disclosed.
