Sigma 70-200mm f/2.8 DG OS HSM Sports - Canon EF, Nikon F, Sigma SA Mount

The Sigma 70-200mm f/2.8 DG OS HSM Sports is a robust telephoto zoom designed for demanding professional use. Part of the Sports line, it features a weather-sealed construction with 11 magnesium alloy components. The optical design includes 9 FLD elements and one SLD element to eliminate chromatic aberration. It incorporates an Intelligent OS system with an acceleration sensor for effective panning, and a customisable AFL button. This lens is built for speed, durability, and high optical resolution. Examine the external barrel for signs of hard use, particularly around the tripod foot and switches. Test the OS modes to ensure the stabiliser functions correctly in both horizontal and vertical orientations. SDS checks the zoom action for smoothness and ensures the autofocus is responsive and accurate. We also inspect the weather seals and the front and rear glass for any marks or coating damage that could affect image contrast.
