The Sigma Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens is a versatile optic well-suited for a variety of subjects, including portraiture, sports, and wildlife. Its advanced optical design incorporates one SLD element and three FLD elements, which help to greatly suppress chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. A Super Multi-Layer Coating has also been applied to individual elements to control flare and ghosting when working in strong lighting conditions.
