    摘要: A zoom lens including a first lens group and a second lens group arranged in sequence from a magnified side toward a reduced side is provided. The first lens group has a negative refractive power and includes a first lens, a second lens, a third lens, and a fourth lens arranged in sequence from the magnified side toward the reduced side, of which the refractive powers are respectively positive, negative, negative, and positive. The second lens group has a positive refractive power and includes a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, and an eleventh lens arranged in sequence from the magnified side toward the reduced side, of which the refractive powers are respectively positive, negative, positive, negative, positive, negative, and positive. The eighth lens, the ninth lens, and the tenth lens together form a triple cemented lens.

    摘要: A zoom lens including a first lens group with a negative refractive power and a second lens group with a positive refractive power is provided. The first lens group includes a first lens, a second lens, and a third lens arranged from an object side to an image side in sequence. The refractive powers of the first, second, and third lenses are negative, negative, and positive sequentially. The second lens group includes a fourth lens, a fifth lens, a sixth lens, and a seventh lens arranged from the object side to the image side in sequence. The refractive powers of the fourth, fifth, sixth, and seventh lenses are positive, positive, negative, and positive sequentially. The first lens group and the second lens group are capable of moving between the object side and the image side.
