The Precision Design EW-78D Lens Hood for Canon EF 28-200mm EF-S 18-200mm IS USM Lens is primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition since the end of the lens is extended you also get the added benefit of some extra protection from accidental impact. Dedicated lens hoods such as the Precision Design EW-78D are designed to match the specific focal length of the lens it was designed for.
