This telephoto zoom employs 13 all-glass elements in 10 groups, including 1 aspherical lens element and 1 ED lens element. The lens demonstrates advanced optical performance across its focal range, producing clear images even when your subject is a long distance away. Its lightweight focusing lens and high-precision motor achieve quick and silent autofocusing.
