The Sigma 70-200mm f/2.8 OS Sports EF Mount is Sigma's latest (as of this writing) flagship telephoto zoom designed specifically for action subjects like sports and wildlife. Its sophisticated optics and build quality offer impressive results thanks to a number of innovative features:

Intelligent Optical Stabilization

Sigma equipped the 70-200mm with the latest algorithm and acceleration sensor that work alongside high-speed autofocus and a Hyper Sonic Motor capable of freezing the quickest movement. Comfortably pan horizontally, vertically, or diagonally plus enjoy stabilization with up to 4 stops of compensation when hand-holding and shooting at slower shutter speeds in low light an ideal function for indoor events or evening shooting.

Smart Build Quality

Use this lens in tough conditions with confidence. The dust and splash-proof design has special sealing all over while the magnesium alloy barrel is both lightweight and tough. The included tripod foot and built-in rotating collar make switching from landscape to portrait orientation fast and easy. It is compatible with any Arca Swiss type clamp or head. This lens is also compatible with Sigma's teleconverters (not included), which create an effective angle of view equivalent to a 98-280mm or 140-400mm lens depending on which teleconverter you use (1.4x or 2x).

Built for Sports, Loved for Portraits

Despite its name, the 70-200mm f/2.8 Sports lens is also a superb portrait zoom. The fast f/2.8 maximum aperture, coupled with the subject-to-distance isolating effects of the long range, creates soft background blur that's perfect for portraiture. Color fringing and other aberrations are prevented due to the use of 10 exclusive low-dispersion glass elements. It exhibits good center-to-edge sharpness and is suitable for pairing with even the highest-resolution EF mount cameras. Go from continuous AF shooting to manual focus with the simple turn of the focus ring, which is a great feature for shooters who need to capture action without sacrificing the ability to easily fine-tune. This lens is compatible with Canon's Lens Aberration Correction function in certain models.

The Sigma 70-200mm f/2.8 OS Sports EF Mount lens is compatible with both full frame and crop frame sensor EF mount cameras. It is versatile enough for all shooting situations but is particularly well suited for sports, wildlife, photojournalism, and portraits.
