Solid magnetic ND filter upgrade
I just picked up a new Sony GM2 lens that requires 82mm filters, so I’ve been slowly upgrading my filter kit to the right size. The Nano-X series is one of K&F Concept’s higher-end lines, so I was glad to add this one. It fits perfectly on my Sony 24–70 GM II and feels very well made right out of the box.
The ND2–ND32 range works exactly as expected, with very minimal X patterning or artifacts, even toward the higher end of the range. The magnetic adapter ring is a big plus—it stays on the lens and makes swapping filters quick and easy, which is great when shooting video or working fast. Overall, this is solid quality glass for the price, and I’ve had consistently good experiences with K&F products. Easy recommendation if you’re looking for a reliable magnetic variable ND.
