Black CNC aluminium magnetic step-up ring 77mm to 82mm

FREEWELL

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

SKU CH-MJQT-QJFGV

Magnetic step-up ring adapts 77mm threads to 82mm and accepts both magnetic and threaded filters

  • Use both magnetic and threaded filters with one ring
  • CNC machined aluminium body prevents light leaks
  • Steps up 77mm lens threads to 82mm filters
  • Black anodised finish eliminates unwanted reflections
  • Compatible with Freewell magnetic filter system

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.

Questions about this item

Does the Freewell magnetic step-up ring include any filters in the box, or must I buy magnetic or threaded filters separately?

The ring itself is the only item supplied; magnetic filters and threaded filters are sold separately.

Should I choose this 77mm to 82mm ring or a different size for my lens?

Match the first number to your lens thread — 77mm here — and the second to the filter thread you want to reach, 82mm in this case.

What does the 77mm to 82mm designation mean when the ring is mounted on my camera?

It lets a lens with a 77mm thread accept any 82mm threaded filter and also works with Freewell magnetic filters.
