UV Filter K&F Nano-X MRC 67 mm — Ultraviolet Camera Lens Filter

The K&F Nano-X MRC 67 mm UV filter is an ultraviolet optical filter for 67 mm threaded camera lenses. Designed to reduce UV haze and provide mechanical protection for the front element, this filter uses a multi-resistant coating (MRC) to maintain high light transmission and minimise surface reflections. The slim profile and standard 67 mm thread allow secure mounting on compatible lenses without altering focal length or colour balance.

Advantages

The multi-resistant coating improves light transmission while reducing flare and ghosting caused by stray ultraviolet and visible reflections. The filter serves as a physical protective barrier against dust, moisture and minor impacts, preventing direct contact with the lens front element. A slim, low-profile frame reduces the risk of vignetting on wide-angle lenses and maintains optical performance across typical shooting situations.

Suitable for

• Landscape photography to reduce UV haze and preserve distant detail
• Travel and outdoor photography where lens protection is required
• Everyday shooting to protect the front element from scratches, dust and fingerprints
• Situations with strong daylight or high-altitude conditions where UV influence is greater

Key specifications

• Filter type: Ultraviolet (UV)
• Diameter: 67 mm thread
• Coating: Multi-Resistant Coating (MRC) for reduced reflections and improved transmission
• Frame: Slim, low-profile metal mount to minimise vignetting
• Optical effect: Reduces UV-induced haze without affecting exposure or colour balance

How to use

Attach the filter to the front of a lens with a 67 mm filter thread by rotating it clockwise until finger-tight; avoid over-tightening. Use the filter in front of the lens for shooting in daylight, especially at high altitudes or in open landscapes where UV haze can reduce clarity. Clean the coated glass with a soft microfiber cloth and lens-cleaning solution as needed; avoid abrasive materials and excessive pressure to preserve the MRC surface.

Usage recommendations

Store the filter in its protective case when not in use to prevent scratches. For long exposures or when using stacked filters, check for potential vignetting on wide-angle lenses. If severe flare appears, try removing the filter to verify whether reflections originate from the filter or another optical element.
