82mm M2 Magnetic Base Ring

The Freewell 82mm M2 Magnetic Quick Swap Empty Base Ring attaches to a lens filter thread, providing a secure mounting point for M1 and M2 magnetic filters. It is built for photographers and videographers who want rapid filter changes during a shoot. The ring preserves optical clarity while protecting the front element from scratches and daily wear.

Check your lens thread size

Verify that your lens has an 82mm filter thread before ordering, as this base ring only fits that specific diameter. Freewell also offers 67mm and 77mm versions for other thread sizes. The ring does not convert standard threaded filters to magnetic operation; it only accepts M1 and M2 magnetic filters.

Thermals noise and power draw

This passive accessory has no electronic components, so it generates no heat, produces no noise and draws no power. It adds negligible weight to the lens barrel and does not affect camera battery life or thermal performance in any shooting scenario.
