The HD nano Mk II coatings are the hardest and most dirt-repellent coatings offered by any manufacturer. The HD nano Mk II coating is 200% harder than conventional coatings, resulting in longer life and better protection. The filter's highly transparent polarizing film offers 25% better light transmission compared to the standard polarizing film used in current photographic filters. This allows almost half a stop more light to enter the lens while achieving the desired polarization effect. The color balance of a standard circular polarizer is maintained while contrast and clarity are improved. With the HOYA HD nano Mk II CIR-PL filter, you can create unique effects in your photos that are not possible with post-processing software. The newly developed coating adheres more firmly and densely to the glass surface due to the nano level. This creates a hard and smooth coating with extremely high density on the glass surface. In addition, the HOYA HD nano Mk II coating has excellent water and oil repellent properties, making maintenance of the filter easy and stress-free.
