HOYA HD nano MkII | Ultra-Hard Anti-scratch Coating Durability Test | Premium grade series

Daily usage and wiping when cleaning the filter wear the coating off. The filter protects from potential physical damage – but the coating should also have extraordinary strength in order to not wear it off during routine maintenance under extreme shooting conditions. If the coating loses its effectiveness, the image quality suffers.
Exclusively developed ultra-hard anti-scratch nano coating is applied onto the HOYA HD nano Mk II's glass surface more firmly and tightly on the nano level than ever before. Due to this, the particles are layered on the glass surface with extremely high density that creates a hard to come off and easy to clean smooth coating.
