A long-reaching zoom within a compact form factor, the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary spans a telephoto to super telephoto range while remaining easily hand-holdable. Its optical design incorporates four Special Low Dispersion elements to control chromatic aberrations and color fringing, for notable clarity and color accuracy, and a Super Multi-Layer Coating has also been applied to reduce ghosting and flare for improved contrast. The front element also features a water- and oil-repellent coating for protection when working in adverse conditions.
Regarding the lens’s physical attributes, it uses a Hyper Sonic Motor to deliver quick and quiet autofocus performance that benefits still and video applications. An Optical Stabilizer also contributes to producing sharp imagery by compensating for the effects of camera shake. Further reinforcing its use in trying environments, rubber sealing is used around the mount to guard against dust and splashes, and the housing is made from Thermally Stable Composite material for consistency when used in a variety of climates. The lens is compatible with the optional Sigma USB Dock for fine-tuning various lens characteristics and for updating its firmware.
The 100-400mm f/5-6.3 DG OS HSM Contemporary lens is available in Canon EF, Nikon F, and Sigma SA lens mounts.
