Athabasca ARK RGND filter is one of the necessary equipment of landscape photography. It uses German Schott optical glass, it is characterized by anti-impact, anti-corrosion and high temperature resistant. Through multi-ultrathin noble metal coating, it has the advantage of low reflection, and low color deviation. Also it uses double-layer water repellent coating.
