The Sirui Ultra Slim S-Pro Nano MC Circular Polarizing Filter increases the color saturation of the image, meaning whiter clouds and a bluer sky, for example. The filter also reduces reflections from non-metallic surfaces (water or glass). Thanks to its high quality, the Sirui Polarizing Filter achieves a polarization rate of nearly 100%.
