K&F Concept 77mm Magnetic Variable ND Lens Filter ND2-ND32 (1-5 Stops) + Magnetic Basic Ring Kit — Nano-X Series, 28-Layer Waterproof Multi-Coating

Fast magnetic attachment: install the supplied Magnetic Basic ring on your lens and the ND2-ND32 filter snaps into place in about 1 second, far quicker than a standard threaded filter (6s). Frame self-lock design prevents the annoying dark "X" cross that can appear on wide-angle and telephoto shots. Optical performance: crafted from Japanese AGC optical glass to maintain accurate color balance and deliver high-definition images without color cast. Variable density control covers ND2–ND32 (1-5 stops) to reduce incoming light and achieve the exposure you need. Durable multi-coating: both glass faces are treated with nanometer coatings (a total of 28 layers) that are waterproof, scratch-resistant and anti-glare, helping protect your lens while improving image quality. Package contents: 1* ND2-ND32 filter + 1* Magnetic Basic ring. Compatibility: fits all 77mm lenses — please verify your lens size before ordering (the diameter number is typically preceded by the "ø" symbol).
