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

Podrobný popis

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

The K&F Concept Nano-X Series 67mm Magnetic Filter 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 kit includes a circular polarizer (CPL) for glare reduction and saturation enhancement (up to 2 stops light loss, 99.8% transmission), a variable neutral density (ND2-32, 1-5 stops) with precise end stops to prevent over-darkening (360° rotation, <1° cross-polarization at extremes), and a Black Mist 1/4 diffusion filter for subtle highlight bloom and skin softening (0.25 density, 95% transmission without color shift). Each filter employs HD optical glass with 28-layer nano-coating (hydrophobic/oleophobic >110°, hardness 9H) for superior durability against scratches, water, and oils, ensuring effortless cleaning with a microfiber cloth. The color-fidelity design maintains neutral tones (no yellowing, <0.1% color cast), while Teflon-infused brass frames enable silent, smooth adjustments—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.
