摘要： A zoom lens includes, in order from the object side, a first lens unit with negative power, a second lens unit with positive power, a third lens unit with positive power, and a fourth lens unit. When the magnification of the zoom lens is changed in the range from a wide-angle position to a telephoto position, spacing between the first lens unit and the second lens unit is narrowed and spacing between the second lens unit and the third lens unit is widened. An aperture stop moved integrally with the second lens unit is interposed between the most image-side lens element of the first lens unit and the most image-side lens element of the second lens unit. The first lens unit has, in order from the object side, a negative lens element and a positive lens element and satisfies the following conditions: 0.15

摘要： The invention relates to a zoom lens and an imaging apparatus incorporating the same. More particularly, the invention is concerned with a zoom lens that is downsized for use with imaging apparatus inclusive of video cameras and digital cameras. The zoom lens comprises a positive first group G1, a negative lens group G2, a positive third group G3, a positive fourth group G4 and an aperture stop S. At least the first group G1 and the second group G2 move for zooming from the wide-angle end to the telephoto end. The first group G1, the third group G3 and the aperture stop S are positioned more on the object side in a state of the telephoto end than in a state of the wide-angle end. The spacing sandwiched between the first group G1 and the second group G2 grows wide, the spacing sandwiched between the second group G2 and the third group G3 becomes narrows, and the spacing sandwiched between the third group G3 and the fourth lens group G4 grows wide. The first group G1 comprises one positive lens and one negative lens, the second group G2 comprises one positive lens and two negative lenses, the third group G3 comprises, in order from the object side, a double-convex positive lens convex on both object- and image-side surfaces and a negative meniscus lens convex on the object-side surface and concave on the image-side surface, and the fourth group G4 comprises on positive lens.
