摘要： A zoom lens includes, a plurality of lens units arranged along an optical axis and configured to move from a wide angle end to a telephoto end during a zooming operation of the zoom lens; a first refractive power variable element whose refractive power is changed in a positive direction by changing shapes of boundary surfaces of different media when zooming from the wide-angle end to the telephoto end; and a second refractive power variable element whose refractive power is changed in a negative direction by changing shapes of boundary surfaces of different media when zooming from the wide-angle end to the telephoto end. When zooming from the wide-angle end to the telephoto end, imaging magnifications of the first refractive power variable element and the second refractive power variable element are increased.

摘要： A zoom lens of the invention has three lens groups. In the zoom lens, magnification change is performed by moving only one lens group among the three lens groups, and focus adjustments is performed by moving one of a first lens group and a second lens group counted from an enlargement conjugate side among the three lens groups. In addition, the zoom lens is approximately telecentric on reduction conjugate side thereof.
