Fantastic magnetic variable ND – Smooth 1-5 stops, quick swap, and superb quality!
I absolutely love this K&F Concept 82mm Magnetic Variable ND Filter (ND2-ND32, 1-5 stops) with the included basic ring kit. The magnetic system is a game-changer - snap the adapter ring onto your lens once (fits my Canon 24-70mm f/2.8 perfectly at 82mm), and then attaching/removing the filter takes literally one second. No more fumbling with threads in the field.
The variable range is spot-on: smooth adjustment from subtle ND2 for brighter conditions up to ND32 for longer exposures or wide-open apertures in daylight. No noticeable X-crossing even at the darker end, and the 28 multi-layer Nano-X coatings handle flare, reflections, and color neutrality beautifully - images stay sharp and true-to-life. Build quality feels premium (slim profile, durable frame), and it's been great for landscapes, portraits, and video where I need quick ND control without swapping filters.
One small nitpick: the filter's outer frame is a bit wider than a standard 82mm lens due to the magnetic design, so my regular 82mm lens cap doesn't fit over it securely. You'll need a larger cap - many users go with 86mm magnetic or pinch caps for these K&F magnetic series filters to cover the whole thing properly. Not a deal-breaker, but worth noting for anyone who wants full protection when stored.
Overall, this is one of the best variable NDs I've used in this price range - reliable, versatile, and way more convenient than traditional screw-ons. Highly recommend for anyone with 82mm lenses looking to upgrade to magnetic quick-swap. 5 stars easy.
