Versatile with its reach, the Canon EF-Mount, Sigma SA-Mount, & the Nikon F-mount 150-600mm f/5-6.3 DG OS HSM from Sigma is a Sports-series lens offering a flexible telephoto zoom range, along with an advanced optical and physical design. A series of low dispersion elements are used to greatly reduce chromatic aberrations and color fringing throughout the zoom range and contribute to greater clarity and color accuracy. A Super Multi-Layer Coating has also been employed to control ghosting and flare for improved contrast when working in strong lighting conditions.
