Heliopan 72mm Rubber Lens Hood (71072H) Heliopans premier 72mm Lens Hood blocks unwanted light rays from entering the lens by way of extending its front end. This prevents lens flair and greatly improves image contrast. The highly functional 72mm Lens Hood rolls back for storage purposes or to convert from normal to wide-angle options. Also, the lens hood features front filter threads that can accommodate filters, lens caps, or other 72mm-threaded accessories. Manufactured from high quality rubber, this lens hood withstand powerful UV rays, extreme temperature and weather conditions without cracking or fading. Our precision cut brass-mounting ring is chemically fused to the rubber element of the hood. This creates an inseparable bond that will guarantee reliable service throughout the life of the product. We do not source any materials outside of Germany in the assembly and construction of our products. All raw materials are prepared and hand-assembled in our factory and do not leave our facility until they are completely inspected by our quality technicians.
