IMPROVED PROTECTION PERFORMANCE AND DURABILITY \n\nThe coating of the filter is not permanent. It gets a damage repeatedly when we clean it with wipes and gets weak as time passes by. The filter can protect the lens from physical damage, but the coating receives the strike first as scratch. When a coating of a filter is solid and scratch resistant, it will be a great advantage. \n\nHIGH TRANSPARENCY POLARLIZING FILM \n\nThe polarizing film is the same as that used in the latest high definition LCD TV screens. It has 25% higher light transmission than standard polarizing film used in current photographic filters. The filter has virtually no effect on the color balance, contrast, or clarity of the final image beyond its polarizing effects. \n\nUltra-Hard nano Coating\n• New 16 layer ultra-smooth, ultra-hard nano coating\n• Stain resistant, water & oil repellent coating makes everyday maintenance easier\n• Ultra-hard surface coating is 200% more scratch resistant than general coating\n\nHD Polarizing Film\n• High Transparency & High Durability UV Absorbing Film\n• 25% Greater Light Transmission than Standard Polarizing Film\n\nHD Frame\n• Very Thin Frame, Front thread to attach lens caps and other filters\n• Press mount technology holds glass securely\n\nThe HD nano CIR-PL filter is using the polarizing film with the high transmission factor, so a picture through a filter and the lens can be recognized clearly by a better contrast. This effect enables a fast shutter valve. This polarizing filter doesn't affect the overall color balance of the shot.
