Lens Hood (Bayonet) for 18-200mm AF-S Lens.
Flower-Type bayonet lens hood provided with select NIKKOR lenses.
Use of specifically engineered Nikon lens hoods is highly recommended.
By reducing the amount of non-essential light falling onto the front lens element, lenses can better achieve their optimum optical performance, producing more saturated images.
In less-than-ideal lighting conditions, the performance difference can be substantial.
