Tamron Lens Hood DA18 for the B008/A18

All Tamron lenses come with lens hoods as standard. Even for shallow hoods based on the the short end of a zoom's focal range, Tamron hoods are designed to produce ample light shielding effects. Tamron also use flower-shaped hoods for models that employ internal focusing, including wide angle lenses. Flower-shaped 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.
