The Tamron FA08 Lens Hood is specially designed for the 200-500mm f/5-6.3 DI LD Lens. Tamron hoods are designed to produce ample light shielding effects. Tamron also uses flower shaped hoods for models that employ internal focusing, including wide angle lenses. Flowershaped hoods remove the parts of the hood that would otherwise show up in the corners of the frame, and conversely extend the hood length to its limits where possible elsewhere, such as the portions covering the long sides of the frame. This design produces hoods that exhibit superb light shielding effects, offering ample protection from stray light even at the telephoto end of high-magnification zooms.
