Top features: - Optical stabilisation to reduce camera shake - High-quality imagery with low dispersion elements - Narrow in on the details with smooth and quiet focusing Optical stabilisation Offering a constant f/2.8 aperture, the Sigma Telephoto Zoom Lens offers a focal length of 70 - 200 mm and a compact, lightweight build that's perfect for portrait and sport photography. Reducing camera shake when you're shooting, Sigma's unique optical stabilisation lets you use shutter speeds four stops slower than would otherwise be possible - perfect for telephoto shooting. Mode 1 is ideal for everyday photography, while Mode 2 is designed to capture panning subjects like sports players or racing cars. High-quality imagery 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 that 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. Narrow in on the details With a Hyper Sonic Motor (HSM), the Sigma 70-200 mm Lens focuses quickly, smoothly and quietly, ideal when shooting video. Rounded diaphragm blades create an attractive, smooth bokeh in out of focus areas, while keeping your foreground subject sharp.
