HK-34 Slip-on Lens Hood

HK-34 Slip-on Lens Hood for AF-S NIKKOR 500mm f/4G ED VR. Slip-on 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.
