The Kenko ECO 40.5mm UV MC Filter is a multi-coated optical glass filter designed to protect your camera lens whilst reducing ultraviolet haze that can diminish image clarity in outdoor photography. Featuring anti-reflection multi-coating on both sides, the filter achieves excellent light transmission to minimise ghosting and lens flare. Its lightweight slim frame and 40.5mm thread size make it compatible with a wide range of lenses. The filter serves as both a UV light absorber and a permanent protective barrier against dust, scratches and moisture, making it an essential accessory for photographers working in varied lighting conditions and environments.
