The Sigma 70-200mm f/2.8 II EX APO Macro HSM telephoto zoom lens has a large maximum aperture of f/2.8 which remains constant throughout the zoom range, an improved optical performance, macro capabilities, and is optimized for digital SLR cameras. It also features super multi-layer coating, which reduces flare and ghosting.
This Macro lens has improved macro capability, with a minimum focusing distance of 3.3' (100cm) and maximum magnification of 1:3.5.

The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function.
This lens can also be used with the 1.4x EX or 2.0x EX APO Tele Converters (optional), becoming a 98-280mm f/4 autofocus telephoto zoom lens or a 140-400mm f/5.6 autofocus telephoto zoom lens respectively.
