Sigma Lens Hood LH876-04 for AF 24-70mm f/2.8 DG OS HSM Art
The Sigma Lens Hood prevents direct or reflected light from entering the 24–70mm f/2.8 Art DG OS HSM lens. It ensures there is no vignetting when capturing photos. The hood also protects the lens from direct impacts from a hard surface. The Sigma Lens Hood comes as a spare or replacement for the one that comes with the lens.
