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 reaches the lens while achieving the same polarization effect, maintaining the color balance of a standard circular polarizer while improving 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 editing software in post-processing. The newly developed coating adheres more firmly and densely to the glass surface through the nano layer than before. This results in particles with extremely high density being 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 simple and stress-free.
