K&F Concept 67MM Nano-X Series Magnetic Filter Kit CPL ND3-32 Black Mist 1/4

The K&F Concept 67mm Magnetic Filter Kit (Nano-X Series) is a versatile 3-filter set including CPL, ND2-32 (variable 1-5 stops), and Black Mist 1/4 for quick magnetic swaps on 67mm lenses. It features a 28-layer nano-coating for scratch and water resistance, color-neutral optics, smooth Teflon rotation, and comes with an adapter ring, 72mm magnetic cap, and a portable pouch, making it ideal for cinematic video and photo effects.

This kit streamlines creative filtration for photographers and videographers, offering a magnetic quick-swap system that eliminates threading delays for seamless transitions between effects on compatible 67mm lenses. The circular polarizer (CPL) reduces glare and enhances saturation (up to 2 stops light loss, 99.8 transmission), while the variable neutral density (ND2-32, 1-5 stops) has precise end stops to prevent over-darkening (360 rotation, <1 cross-polarization at extremes). The Black Mist 1/4 diffusion filter provides subtle highlight bloom and skin softening (0.25 density, 95 transmission without color shift). Each filter is made of HD optical glass with a 28-layer nano-coating (hydrophobic/oleophobic >110, hardness 9H) for superior durability against scratches, water, and oils, ensuring easy cleaning with a microfiber cloth. The design maintains neutral tones (no yellowing, <0.1 color cast), while Teflon-infused brass frames enable silent, smooth adjustments, which is critical for run-and-gun video with on-camera mics. Stacking compatibility requires larger sizes (e.g., 77mm kit stacks 82mm filters), and the included magnetic adapter ring (67mm thread, 2 mm profile) plus 72mm magnetic lens cap provide secure, vignette-free mounting. Packaged in a hook-and-loop pouch (compact 10 x 15 x 5 cm), this lightweight kit (<200 g total) fits in camera bags for on-location use, empowering balanced exposure control, polarization, and atmospheric diffusion in portraits, landscapes, or dynamic footage.
