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 39.4" (100 cm) and maximum magnification of 1:3.5. All
zooming and focus movement is achieved internally, allowing for a constant
length and great resistance to dust and moisture. It comes rendered in a hard
coated, baked black EX crinkle finish.
The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well
as full-time manual focusing capability for Sigma, Canon, and Nikon mount
lenses.
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.
