Product Description

The Sigma 120-300mm F2.8 DG HSM OS is the first lens introduced into Sigma's Sports category. Designed for full frame cameras but can work with APS-C sized sensors as well, the 120-300 F2.8 has a large aperture and versatile focal length, ideal for a wide range of photography. Equipped with state of the art technology such as a Hyper Sonic Motor (HSM), an Optical Stabilizer (OS) and inner focusing and zooming. The HSM allows for a quiet, fast, and accurate autofocusing while the OS compensates for camera shake while shooting by hand. Two FLD glass elements, which have performance equal to fluorite, are incorporated with one SLD element to reduce color aberration at the highest degree. The Sports category offers not only a higher level of customization through the Sigma USB dock, but also has a dust and splash proof design.

Hi guys i am thinking about buying a sigma 120-300mm f2.8 lens for my nikon d7000 body.Will they work well together?I will be using this set up for fast moving sports.

The OS is pretty good on that lens so it should work well.  But you are really a lot better off asking in the Nikon forum as they can answer how it behaves on a Nikon body, most here will have used the Sigma lens on a Sigma body. Continue Reading

They should work well together, but consider the crop sensor magnification, as this a full-frame lens. Continue Reading
