Sigma 58mm DG Multi-Layer Coated Wide Circular Polarizer Filter

The Sigma 58mm DG Multi-Layer Coated Wide Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions.
