The Athabasca Razor CPL is an ultra thin circular polarizer, allowing you to eliminate polarizing light from your images. Cutting edge technology makes the filter thickness as thin as only 3.17mm and reduces vignetting when fixed to any wide-angle lens. The Razor circular polarising filter is also stain proof and scratch resistant. 

CPLs are used to increase colour saturation, decrease reflections on non-metallic surfaces such as water or glass, help eliminate atmospheric haze, and darken skies.

How to Use:

Fix the Razor CPL directly to the front lens. Rotate the Razor CPL and observe the polarized light source through the LCD or viewfinder, until the polarized light weakens or disappears as expected.
