120-300mm f/2.8 DG OS HSM Zoom Lens

120-300mm f/2.8 DG OS HSM Zoom Lens is ideal for sports, action and wildlife photography, thanks to its fast f/2.8 max aperture and a focal length range of 120-300mm on a full frame camera (DG lens). The presence of HSM (Hyper-sonic Motor) technology ensures that the lens has super-silent auto-focusing plus optical image stabilization makes the lens that much more shake free when hand-held. The lens is designed using 2 FLD and 1 Special Low Dispersion (SLD) glass elements and has a total of 23 elements arranged in 18 groups.

The Sigma 120-300 F2.8 DG HSM OS is the first lens introduced into the Sports category for SigmaÕs Global Vision. 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. Though placed in the Sports category, the 120-300 F2.8 is also great for nature, automotive, wildlife, and everything in between. Equipped with state of the art technology such as a Hyper Sonic Motor (HSM), an Optical Stabilizer (OS) and Inner Focusing and Zooming, the 120-300 F2.8 ensures sharp and beautiful images. 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.
