This 37mm SHD ULCA WMC UV Filter from Benro is primarily designed to eliminate ultraviolet light, avoiding a degradation of image contrast. This is particularly noticeable when photographing outdoor scenes, where a UV filter will work to combat the faded blue or white effect that ultraviolet light can cause. 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 aluminium alloy filter ring and high-quality optical material with a multi-layered anti-reflection coating. A ULCA low-colour multi-layer coating provides high light transmission and low reflectivity to reduce glare. The WMC coating offers scratch-resistance and repels water and oil.
