When the color saturation increases, the sky becomes bluer and the water becomes clearer. It can also be used as an ND filter, reducing light by 1 to 2 stops. To remove reflections, simply rotate the CPL filter properly. Made of German Schott B270i HD glass, this filter has AR coating that is waterproof, stain-resistant, mold-resistant, and scratch-resistant, with less color cast and an ultra-thin frame processed by CNC. There is no vignetting even when shooting with an ultra-wide-angle lens. It can be magnetically attached securely to the SmallRig magnetic filter adapter ring.
