SIGMA 120-300mm F2.8 DG OS HSM Sports Nikon

A top-tier telephoto lens for users who require uncompromising picture quality combined with high luminosity. It was designed for full-frame cameras, but can work with APS-C sized sensors as well. Its variable focal length makes this model really versatile, and although it is classified as a sports lens, it is fully suitable for nature photography, cars, wildlife, and other similar usage. It is equipped with a hypersonic motor (HSM) for quiet and accurate autofocus and optical image stabiliser (OS), which compensates for camera shake while shooting by hand.
The design uses two FLD glass elements, whose optical performance is comparable to fluorite except they are also lighter, plus a CLD element for reducing chromatic aberration. The Sport series lenses also offer a high degree of customisation through the Sigma USB dock (sold separately) and are resistant against dust and water splashes.

In case of any problems with focus (front/back focus), it is necessary to adjust the lens via the Sigma dock station.
