Sigma 500mm f/5.6 DG DN OS Sports - Sony E, L-Mount

The Sigma 500mm f/5.6 DG DN OS Sports is a compact, lightweight super-telephoto prime designed for full-frame mirrorless systems. By utilising Low Dispersion glass elements, Sigma has significantly reduced the lens's physical footprint without compromising on image quality. It features a high-speed HLA autofocus motor and an intelligent OS2 algorithm for effective optical stabilisation, making it suitable for handheld wildlife and sports photography. When purchasing used, inspect the rear filter slot and the aperture ring for smooth operation. SDS checks the lens for any internal dust and ensures the autofocus is responsive and accurate at long distances. Given its lightweight construction, the external barrel should be checked for scuffs, though the magnesium alloy parts are durable. Verify that the tripod socket turns smoothly and locks tightly.
