FREEWELL 77mm-82mm Magnetic Step-Up Ring camera filter

What it is and who it’s for

The Freewell 77mm-82mm Magnetic Step-Up Ring adapts lenses with a 77 mm filter thread to accept 82 mm accessories. It combines a traditional screw thread with a magnetic interface so photographers can mount both threaded and Freewell magnetic filters on the same ring. CNC-machined aluminium with a black finish reduces reflections and light leaks during shooting.

What to check before ordering

Confirm that your lens has a 77 mm front thread; the size is usually printed under the lens cap or on the barrel. The ring steps up to 82 mm, so any filter or accessory you intend to use must match that diameter. Ensure you want the magnetic locking feature, which is designed specifically for Freewell magnetic filters alongside standard threaded filters.

What it replaces and when the jump is worth it

It replaces a conventional step-up ring that only accepts threaded filters, adding the ability to snap on magnetic filters without extra adapters. The upgrade makes sense if you already own or plan to buy Freewell magnetic filters and want a single ring that handles both mounting systems, saving time when switching filter types in the field.
