Take full command of exposure with the K&F Concept 37mm Nano-X Variable ND8-ND128 Filter—delivering 3 to 7 stops of adjustable neutral density without the dreaded “X” cross, even on wide-angle or telephoto lenses. Crafted from imported Japanese AGC optical glass, it ensures zero color cast, maximum sharpness, and true tonal balance. Advanced 28-layer nanometer coatings provide robust waterproof, scratch-resistant, and anti-glare protection while maintaining optical purity. The self-locking 7.4mm ultra-slim CNC aluminum frame eliminates vignetting down to 28mm focal length and offers non-slip grip for fast, secure installation. Perfect for video run-and-gun, long-exposure landscapes, or wide-aperture portraits in bright light—pair with a 40.5mm lens cap/hood. Verify your lens thread (“ø37”) before purchase.
