Leica Lens Hood TL 35mm/60mm ASPH. Silver
Originally included with the Leica Summilux-TL 35mm & APO-Macro-Elmarit-TL 60mm lenses, this Lens Hood is available as a replacement or spare. The lens hood's purpose is to block stray light from entering the lens, thus reducing the chance of ghosting and flaring. In addition, since the end of the lens is extended, you also get the added benefit of extra protection from accidental impact.
