Hoya CIR-PL HD Nano 82mm Filter

Boosted protection and performance. The HD nano CIR-PL coatings are the hardest, most scratch-resistant and stain-resistant available from all manufacturers. Regular filter coatings can be easily damaged over time by excessive wiping or abrasive cleaning cloths. HD nano coatings are 200% tougher for increased longevity and better protection. High Transmisstion Polarizing Film: The HD nano CIR-PL polarizing film offers a superior light transmission of 25% compared to standard polarizing films used in current photographic filters. This means nearly half the light enters your lens while maintaining the same polarization effect as a standard circular polarizer, preserving the color balance. Polarizing filters reduce unwanted reflections from non-metallic surfaces like water and glass, as well as reflected light from humidity and atmospheric pollution, creating a deep blue sky. You'll see the difference when you turn the filter. In addition to a deeper blue sky, it reduces reflections, makes foliage greener in landscapes, and improves clarity and contrast in your photos.
