The FUSION ONE NEXT UV has an 18x anti-reflective coating on both sides of the filter glass, which ensures extremely high light transmission and reduces the likelihood of reflections caused by the filter. The coating also has dirt and water repellent properties that protect the filter glass from fingerprints and smudges and make cleaning quick and easy. The glass of the FUSION ONE NEXT UV is made of HOYA's professional optical UV glass for the highest image quality and a sharp UV cut.
