Part of SIGMA’s Sports line of telephoto lenses, the 70-200mm F2.8 DG OS HSM | Sports is the new flagship that meets the needs of professional photographers. The optical design provides excellent resolution from centre to corners, while eliminating chromatic aberration. The large aperture ensures smooth bokeh – ideal for portrait photography. Dust- and splash-proof construction means you can use the lens in challenging conditions. SIGMA’s Hyper Sonic Motor makes autofocus fast and quiet, while the Intelligent OS system provides sharp images when using longer shutter speeds. As with all recent SIGMA lenses, many settings can be customised via the SIGMA USB DOCK.
