K&F Advanced UV Filter Nano-X Pro MRC 86mm (KF01.1413)

The K&F Advanced UV Filter Nano-X Pro MRC 86mm is a screw-in lens filter designed to reduce ultraviolet light and protect the front element of compatible 86 mm thread lenses. The filter integrates a multi-resistant coating (MRC) to minimise reflections and improve light transmission, while the Nano-X surface treatment helps resist moisture, oil and dust. It is intended for outdoor, landscape and travel photography where ultraviolet haze can reduce image clarity and when a durable protective layer on the front element is required.

Advantages

This K&F Advanced UV filter provides passive UV attenuation without affecting colour balance, helping to reduce atmospheric haze in bright daylight. The multi-resistant coating lowers internal reflections and flare, improving contrast and sharpness across the frame. The Nano-X surface finish makes the glass easier to clean and more resistant to fingerprints, water and smudges. The slim-threaded metal frame helps minimise vignetting on wide-angle lenses while maintaining secure screw-in attachment.

Suitable for

• Outdoor and landscape photography to reduce UV haze and improve distant detail
• Travel and street photography where lens protection is needed against dust and minor impacts
• Wide-angle lenses with 86 mm filter thread where a slim filter profile reduces vignetting
• Situations requiring improved flare control and easier front-glass maintenance

Key specifications

• Filter type: UV (ultraviolet) screw-in filter
• Diameter: 86 mm filter thread
• Coating: Multi-Resistant Coating (MRC) with Nano-X surface treatment
• Frame: Slim metal ring to reduce vignetting on wide-angle lenses
• Optical effect: Reduces UV transmission and atmospheric haze without altering colour balance

How to use

Screw the filter gently onto the front of any lens with an 86 mm thread until snug; avoid overtightening. Use the filter in bright daylight or high-altitude conditions to reduce ultraviolet haze and preserve clarity of distant subjects. For protection, keep the filter mounted when transporting the camera to prevent scratches and dust on the front element. To clean, use a blower or soft brush to remove loose particles, then a microfiber cloth or lens tissue with appropriate cleaner to remove smudges from the coated surface.

Usage recommendations

For best results, use the filter on lenses that accept 86 mm threads and pair it with a lens hood to further reduce stray light. When shooting long exposures or in low light, verify focus and exposure settings as any additional glass may require minor adjustments. Store the filter in its protective case when not in use to preserve the Nano-X coating and mechanical threads.
