The worlds Thinnest CPL filter

Available in 67, 72, 77 and 82mm filter thread sizes.

The Athabasca Razor CPL is an ultra thin circular polariser, allowing you to eliminate polarising 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 polarised light source through the LCD or viewfinder, until the polarised light weakens or disappears as expected. A CPL works best at 90 degrees from the sun.
