Advanced Lens Coating Technology SWC (Subwavelength Structure Coating)
The last challenge in lens design is the pair of phenomena known as ghosting and flare. Using a completely-new coating technology, SWC, Canon succeeded in overcoming those phenomena. By taking a cue from insect eyes and other mechanisms existing in nature and applying leading-edge nanotechnology, Canon realized the creation of a non-reflective structure.
