The Sigma LH686-01 Lens Hood is specially designed to prevent unwanted direct and indirect light from entering your Sigma 30 mm f1.4 DC HSM lens. It is constructed using premium-quality materials for excellent durability and to match the optics and design of your valuable glass. Featuring a ridged interior with an anti-glare matte finish, this lens hood helps to minimise glare, flare, and internal lens reflections to ensure maximum image contrast and quality. Additionally, the Sigma LH686-01 extends out from the front lens element to offer extra protection from scratches, dust, moisture, fingerprints, and damages when the lens is not in use. This spare or replacement lens hood is not compatible with the 30 mm f1.4 EX DC HSM (300) lens.
