A Nano Surface Coating minimizes lens flare and ghosting for better contrast in bright, backlit conditions. The lens features a POWER O.I.S. system to minimize camera shake, beneficial for handheld shooting in challenging lighting. A stepping AF motor and internal focusing mechanism ensure quick, quiet focusing, suitable for both photo and video. The lens is weather-sealed against moisture and dust, making it reliable in harsh environments. Its constant f/2.8 aperture ensures consistent performance throughout the zoom range, while the rounded seven-blade diaphragm contributes to pleasing bokeh quality.
