This high-performance, high-power zoom lens delivers focal lengths extending from an unprecedented 16 mm at the wide-angle end up to a long-range telephoto 300 mm! The lens construction features 16 elements in 12 groups. This includes three molded-glass aspherical elements, one hybrid aspherical element, two LD (low dispersion) elements, one XR (extra refractive index) glass element, and one element of UXR (ultra-extra refractive index) glass, which has a greater refractive index than XR. The full use of specialized glass elements in the design contributes to thorough compensation of optical aberrations. In addition, the use of the coating technology for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting and assures sharp, crisp, high-contrast images.
