K&F Concept Nano-X Series 67mm Variable ND4-64 (2-6 Stops) + CPL 2-in-1, 28 Multi-Coated Polarizing & Neutral Density Lens Filter

Two filters in one: this K&F Concept Nano-X Series piece combines a variable neutral density and a circular polarizer, giving you both ND and CPL functions in a single 67mm unit. The variable ND range covers ND4 to ND64 (2-6 stops), letting you control exposure on overcast or very bright days. The CPL element reduces unwanted glare from non-metallic surfaces while boosting color saturation and contrast. Engineered to avoid the common variable-ND "X" artifact on wide-angle shots, it uses advanced anti-cross technology so your images remain clean. Optically, the filter is built from imported AGC glass and features 28 multi-layer coatings. It permits only 0.2% light transmittance, and the surface is waterproof and scratch-resistant to help protect your lens. The frame is aluminum alloy with a CNC-Non-slip finish and a putter-style adjustment for easy stop changes; five stop markings from Min(ND4) to Max (ND64) are printed on the ring for precise setting. For this 67mm ND filter, use a 72mm lens cap or hood. Compatible with all 67mm lenses—please confirm your lens thread size before ordering (the number beside the "ø" symbol indicates the diameter).
