K&F Concept Nano-C HMC UV Filter 72mm Ultra-Slim Protection Lens Filter

For photographers who refuse to compromise image quality for lens protection, the K&F Concept Nano-C HMC UV filter in 72mm delivers exceptional clarity and durability. Unlike standard UV filters that can introduce softness or color casts, this filter uses 18 layers of hard multi-coating on Japanese AGC optical glass to maintain over 99.6% light transmittance. The result is a protective barrier that is virtually invisible in your final images.

Highlights

• 72mm diameter fits a wide range of standard and telephoto lenses
• Nano-coated surface repels water, oil, and dust for easy cleaning
• Ultra-slim 3.3mm aviation aluminum frame prevents vignetting on wide-angle lenses
• Double-threaded design allows stacking filters or attaching lens caps
• Hardened coating provides scratch resistance for long-term reliability

In daily use

Mount the filter once and leave it on your lens as a permanent shield against scratches, dust, and accidental impacts. The nano-coating causes water to bead up and roll off, while fingerprints and smudges wipe away with a single pass of a microfiber cloth. When shooting in bright conditions, the UV filtration reduces haze and improves contrast, especially in landscapes and high-altitude scenes. The slim profile ensures no dark corners even at 16mm on full-frame cameras.
