UV Ultra Low Reflection filter K&F Concept Nano-X MRC 52 mm (52mm)

K&F Concept UV Ultra Low Reflection filter Nano-X MRC 52 mm is a slim, screw-in camera lens filter designed for lenses with 52 mm threads. It combines ultraviolet light reduction with a durable multi-resistant coating to minimise haze and internal reflections while providing a protective barrier for the front element. The filter is intended to preserve image clarity in outdoor and bright-light conditions and to protect the lens from dust, moisture and minor mechanical damage.

Advantages

The Nano-X MRC coating reduces surface reflections and repels water, oil and fingerprints for easier cleaning and longer-lasting optical performance. Its slim profile helps prevent vignetting on wide-angle lenses while maintaining a secure, threaded fit. The optical glass is engineered to transmit visible light with minimal colour shift, supporting natural-looking images and consistent exposure without altering autofocus or metering behaviour.

Suitable for

• Landscape and outdoor photography where UV haze reduction improves distant detail
• Travel and street photography to protect the front element from dust and incidental contact
• Everyday use when a durable protective filter is preferred over leaving the lens exposed

Key specifications

• Filter type: UV, ultra-low reflection
• Thread size: 52 mm
• Coating: Multi-Resistant Coating (MRC) with Nano-X water- and oil-repellent properties
• Profile: Slim design to reduce vignetting on wide-angle lenses
• Material: Optical glass with coated metal ring

How to use

Screw the filter gently onto the front filter thread of a compatible 52 mm lens until it is secure; avoid over-tightening. Use the filter in front of your lens for general UV reduction and continuous front-element protection. Clean the coated surface with a soft microfibre cloth and, if necessary, a small amount of lens cleaning solution compatible with coated optics. When storing the lens and filter together, keep them capped to prevent dust accumulation.

Usage recommendations

For optimal results in bright outdoor conditions, use the filter together with proper lens hoods to minimise stray light and flares; check for vignetting when using ultra-wide focal lengths and remove or replace with an ultra-slim filter if necessary.
