Camera lens filter K&F Concept Nano X MCUV 77mm – multi-coated UV protection, 77 mm thread

K&F Concept Nano X MCUV 77mm is a multi-coated ultraviolet (MCUV) camera lens filter with a 77 mm thread, designed to reduce UV haze and provide basic front-element protection. The Nano X multi-coating reduces surface reflections and ghosting, helping to preserve accurate color rendition and contrast while maintaining image sharpness. The filter is lightweight, thin-profile and easy to mount on lenses with a 77 mm filter thread, making it convenient for landscape, travel and everyday photography.

Advantages

The Nano X multi-coating provides multiple anti-reflective layers that minimize flare and ghosting across visible wavelengths, which helps retain natural colors and contrast. As a UV filter, it reduces atmospheric haze and improves clarity in bright daylight shooting. The slim, metal filter ring keeps vignetting to a minimum on wide-angle lenses while offering a durable protective barrier for the front element against dust, moisture and minor impacts. The 77 mm thread is a common standard, ensuring compatibility with many professional and consumer lenses.

Suitable for

• Landscape photography in bright daylight and coastal or high-altitude conditions
• Travel photography where lens protection and quick mounting are needed
• Everyday shooting to protect the front element from dust, fingerprints and light scratches
• Outdoor portrait and street photography to reduce UV haze and improve clarity

Key specifications

• Filter type: Multi-coated UV (MCUV)
• Filter diameter (thread): 77 mm
• Coating: Nano X multi-anti-reflective coating
• Frame material: Metal, slim profile to reduce vignetting
• Optical effect: Reduces UV haze, minimizes reflections and ghosting

How to use

Screw the filter onto the front thread of any lens with a 77 mm diameter until it is snug; avoid overtightening. Use the filter on clear, clean glass for best optical performance—clean with a blower, lens brush or microfiber cloth and appropriate cleaning fluid if necessary. When composing images, evaluate any change in flare or reflections under strong light sources and remove the filter for specialized optics where UV filtering is not desired. For stacking filters, be aware that the slim profile reduces but may not eliminate vignetting on very wide-angle lenses.

Usage recommendations

Keep the filter cap on during transport to protect the glass. For critical long-exposure or astrophotography, test images with and without the MCUV filter to confirm there is no unwanted effect on exposure or star shapes. Store in a padded pouch and avoid contact with sharp objects to maintain the multi-coating integrity.
