The 67-82mm Freewell Magnetic Step-Up Ring allows you to screw threaded filters onto compatible lenses or magnetically adapt Freewell magnetic filters.
Filters that have 82mm rear threads can be screwed onto lenses featuring 67mm front threads. For magnetic attachment, screw this adapter onto a lens that has 67mm front threads, and then magnetically attach Freewell's 82mm magnetic filters onto the front of this adapter ring.
