This 77mm PD HD WMC Circular Polarising Filter from Benro is primarily designed to eliminate polarized light, producing increased colour saturation. This is particularly noticeable when photographing outdoor scenes, where a CPL filter will work to combat atmospheric fog to deepen the blue of the sky, highlight white clouds, and eliminate reflected light bringing detail back in to reflective surfaces such as water or glass. It will not affect picture colour, and is slim enough to avoid vignetting when used with most wide angle lenses. All filters will also offer a degree of protection for the front element of your lens against moisture, dust and scratching. It features a rugged aluminum alloy filter ring and high quality optical material with a multi-layered anti-reflection coating.
Please note that the item pictured is indicative only and this listing is for the 77mm filter.
