The Okko 46mm Pro Protect UV Filter is a high-transparency optical glass filter designed to protect your lens from dust, moisture, and accidental scratches. Engineered with a slim profile to prevent vignetting, it features a multi-layered coating that effectively filters out ultraviolet light, reducing haze and improving image contrast in bright conditions. It is a "set-and-forget" accessory that provides essential peace of mind without affecting the colour balance or sharpness of your high-performance lenses.
