With an impressive zoom range and optical image stabilisation, shooting faraway subjects like sports and wildlife is easy with the Sigma 70-200 mm f/2.8 EX DG OS HSM Telephoto Zoom Lens. Handheld zoom The 70-200 mm Lens is compatible with the Canon EF mount, offering 35 mm coverage on full-frame bodies, while the fast f/2.8 aperture remains constant throughout the entire zoom range. Camera shake is significantly reduced thanks to Optical Stabilisation (OS) technology which lets you shoot at shutter speeds approximately four stops slower than otherwise possible, ideal when shooting portraits and sports handheld. Quality construction Delivering excellent optical performance, the 70-200 mm Lens features two “F” Low Dispersion (FLD) glass elements, which perform equally to fluorite glass, and three Special Low Dispersion (SLD) glass elements which provide excellent correction of colour aberration. Ghosting and flare is kept at a minimum thanks to a Super Multi-Layer Coating which helps ensure high contrast, detailed images. Fast autofocus With a Hyper Sonic Motor (HSM), the Sigma 70-200 mm Lens focuses quickly, smoothly and quietly, ideal when shooting video. The inner zooming system means the overall length of the 70-200 mm Lens doesn’t change during zooming, making it easier to handle, while internal focusing prevents the front lens rotating, ideal when using polarising filters and lens hoods. Rounded diaphragm blades create an attractive, smooth bokeh in out of focus areas, while keeping your foreground subject sharp. Portable enough for use in the field, bring the action closer with the Sigma 70-200 mm f/2.8 EX DG OS HSM Telephoto Zoom Lens.
