UV filter K&F Concept Nano-X MRC 55mm for camera lenses

The UV filter K&F Concept Nano-X MRC 55mm is a circular lens filter designed to attach to lenses with a 55mm thread. It reduces ultraviolet light transmission to minimize atmospheric haze and improve clarity in outdoor scenes, while the Nano-X multi-resistant coating (MRC) helps lower surface reflections and maintain accurate color reproduction. The filter also serves as a physical barrier to protect the front element of the lens from dust, scratches and light moisture without affecting focal length or exposure settings.

Advantages

The Nano-X MRC surface provides multiple layers of anti-reflective treatment to increase light transmission and decrease ghosting and flare. Constructed in a slim, low-profile metal ring to fit compact lens assemblies and prevent vignetting on wide-angle optics, the filter is lightweight and maintains optical performance. The hydrophobic and oleophobic properties of the coating make cleaning easier and reduce smears from fingerprints and water droplets. Compatible with screw-in 55mm threads, it installs quickly and unscrews for storage.

Suitable for

• Landscape and outdoor photography to reduce atmospheric haze
• Travel and street photography for front-element protection
• Everyday shooting when additional lens protection is needed
• Use with wide-angle and standard prime or zoom lenses that accept 55mm filters

Key specifications

• Filter type: UV (ultraviolet) circular filter
• Mount thread size: 55mm screw-in
• Coating: Nano-X multi-resistant anti-reflective coating (MRC)
• Frame: slim, low-profile metal ring to reduce vignetting
• Primary functions: UV light reduction, haze reduction, front-element protection

How to use

Screw the filter onto the lens’ 55mm front thread until it is gently hand-tight; avoid overtightening. Compose and focus as usual — the filter does not change focal length or exposure metering. For removal, hold the lens steady and rotate the filter counterclockwise. Clean the filter surface with a microfiber cloth and appropriate lens cleaning fluid if necessary, wiping gently to avoid scratching the coating.

Usage recommendations

Use the UV filter outdoors when shooting in bright daylight or in hazy conditions to reduce ultraviolet haze without altering color balance. Keep the filter in its protective case when not in use and avoid excessive mechanical force when mounting to preserve the threads and coating performance.
