Hoya HD Nano Mk II CIR-PL Filter

The HD nano Mk II coatings are the hardest, scratch-resistant, and dirt-repellent coatings offered by any manufacturer. The HD nano Mk II coating is 200% harder, providing a longer lifespan and better protection. The highly transparent polarizing film has 25% better light transmission than the standard polarizing film used in current photographic filters. This means that nearly half a stop more light enters the lens while achieving the same polarization effect, maintaining the color balance of a standard circular polarizer while enhancing contrast and clarity. With the HOYA HD nano Mk II CIR-PL filter, you can create unique effects in your photos that cannot be achieved with post-processing software. The newly developed coating adheres more firmly and densely to the glass surface through the nano layer than before. This results in extremely high-density particles layered on the glass surface, leading to a hard and smooth coating. In addition to its ultra-hard and smooth properties, the HOYA HD nano Mk II coating features excellent water and oil-repellent properties, making filter maintenance easy and stress-free.
