Prevent unwanted stray light from entering your Sigma 17-70mm f/2.8-4 DC Macro lens with this dedicated Lens Hood from Sigma, which is manufactured to match the design and optics of your valuable glass. This petal-shaped hood features a ridged interior surface to further restrict unwanted light from reaching your lens and creating unwanted flare. Additionally, because the hood extends out from the front lens element, you get extra protection from accidental impact and the elements.
