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

120-300mm f/2.8 DG OS HSM Zoom Lens is a telephoto lens classified by Sigma in the sports category and designed for the larger sensor based full frame DSLRs, though it also works with APS-C DSLRs with a corresponding increase in focal length. The lens covers a focal length of 120-300mm on full frame DSLRs and 180-450mm on APS-C DSLRs. It encompasses optical image stabilization (OS), a fast constant aperture of f/2.8, HSM (Hyper-sonic Motor) for quiet auto-focusing and 1 Special Low Dispersion (SLD) & 2 FLD elements.

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.

USB Dock Compatibility

Sigma has developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. In addition, the lenses from our Sports line have customizable AF speed, focus limiter and OS function. The ÒCustom Mode SwitchÓ is the device for further customization on the dedicated lenses.
