Lens Hood (Bayonet) for 20mm f/2.8 D-AF Lens.
Use of specifically engineered Nikon lens hoods is highly recommended.
In less-than-ideal lighting conditions, the performance difference can be substantial.
Optional bayonet lens hood for select NIKKOR lenses.
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.
HB-4 Bayonet Lens Hood 1 1
HB-4 Lens Hood Plastic and looked not very strong. It is the only hood option for an ultra wide lens like AF20/2.8D. Any other choice? A bit expensive for the material use but just right for the design for no dark corners. The ultra wide lens can have dark corners if used with something else as hood other than the HB-4.
