Coated, magnetic VND that’s built for regular use
A magnetic variable ND is one of those tools that immediately speeds up your workflow—especially when you’re moving between sun, shade, and interiors and want to keep shutter speed consistent for video. This K&F CONCEPT Nano-X set includes an 82mm ND2–ND32 (1–5 stops) variable ND plus a basic magnetic ring, so once the ring is installed, the filter snaps on and off quickly instead of slowly threading every time.
In a typical production setup, the 1–5 stop range is a practical sweet spot for everyday daylight control. The magnetic system is the real quality-of-life upgrade here: you can pop the ND off for a quick indoor moment, then snap it back on without breaking pace. The multi-layer coatings and water-resistant/scratch-resistant build are also helpful for real-world shooting—fingerprints, dust, and light moisture happen, and this kind of coating generally makes cleaning less stressful.
Pros
• Magnetic swap is genuinely fast once the ring is installed, which helps in run-and-gun shooting
• 1–5 stop range is versatile for daylight control while keeping creative settings consistent
• Coatings help with cleaning and reduce surface reflections in harsher light
• Solid build feel for a filter that’s likely to live on a lens during outdoor shoots
Cons
• Requires keeping the magnetic ring on the lens, which may affect how some caps/hoods fit depending on your setup
• If you frequently switch lenses, you may want extra rings to keep the magnetic workflow consistent
• As with any variable ND, results can vary slightly at the extremes depending on lens and shooting conditions (worth keeping in mind)
Final Thoughts
If your priority is functionality—fast, repeatable exposure control—this kit delivers a noticeable quality-of-life improvement, and the coatings help protect image quality in real shooting conditions. It’s a strong fit for creators using 82mm lenses who want a quick-swap solution that keeps color accuracy looking natural and makes day-to-day shooting more efficient. As a practical, reusable tool that speeds up work in the field, it offers solid value.
