Feature: 1. 99.99% Depolarization Rate: Double sided 18 layer coating, optical grinding of premium optical glass, fine optimization of the glass, reducing the color cast of the polarizing film. 2. Why Use CPL Filter: CPL Filter can eliminate reflections, restore the texture of the object itself, emphasize the contrast of the picture, make the sky bluer and the clouds more three dimensional, restore the original color of the scene, increase the saturation of the picture, and create a landscape image with rich depth. 3.

AGC Professional Optical Glass: 18 layers of coating are carried out on the basis of high definition glass, which is waterproof, scratch resistant and oil resistant while maintaining telephoto high definition. 5. Universal Screw Port: Mount MRC CPL filter, you can also install the same size light reduction filter, star filter, protection filter, soft light filter, etc. 6. Emphasize Contrast and Restore Color: Polarizers can eliminate stray light on non metallic surfaces, and can also increase object saturation, enhance three dimensionality, highlight layers, and restore their true colors.
