K&F UV Ultra Low Reflection Nano-X MRC Filter 46 mm (KF01.2459) – UV protection, multi-resistant coating

The K&F UV Ultra Low Reflection Nano-X MRC Filter 46 mm is an optical UV filter designed to reduce ultraviolet light transmission and minimize atmospheric haze for clearer outdoor images. Its ultra low reflection glass and Nano-X multi-resistant coating (MRC) lower surface reflections and flare, while the slim 46 mm threaded mount maintains compactness and compatibility with lenses that accept 46 mm filters. The filter also serves as a protective barrier for the front element against dust, fingerprints and light scratches without altering color balance or exposure in visible light.

Advantages

The Nano-X MRC construction combines ultra low reflection glass with a multi-resistant coating that repels water, oil and dust and reduces flare from bright light sources. The slim profile reduces vignetting on wide-angle lenses while the threaded aluminum frame provides stable attachment and easy handling. The filter is optically neutral in visible light, so it preserves image color fidelity and exposure while offering continuous front-element protection during travel and outdoor shooting.

Suitable for

• Landscape photography to reduce atmospheric haze and improve distant detail
• Travel and street photography where front-element protection is required
• General-purpose outdoor shooting under bright daylight conditions

Key specifications

• Filter type: Ultraviolet (UV) / protection filter
• Thread size: 46 mm
• Coating: Multi-resistant coating (MRC) with Nano-X ultra low reflection treatment
• Frame: Slim aluminum mount to reduce vignetting
• Optical effect: Reduces UV transmission and minimizes flare and reflections

How to use

Screw the filter onto the front of a lens with a 46 mm thread until it is secure but not overtightened. Use the filter on outdoor shoots where UV haze may affect distant detail or when you want to protect the front element from dust and incidental contact. Clean the coated surface with a soft microfiber cloth and a small amount of lens-safe cleaning fluid if needed; avoid abrasive materials. Remove the filter when specialized filters (e.g., polarizers or graduated filters) with different thread mounting are required for a shot.

Usage recommendations

For best results, mount the K&F UV Nano-X MRC filter on lenses with a 46 mm thread and store it in a protective pouch when not in use. When photographing sunsets or bright light sources, check for any residual flare and adjust angle or remove the filter if necessary. Regular gentle cleaning will preserve the multi-resistant coating and optical performance.
