The Freewell 62-72mm Magnetic Step-Up Ring enables you to attach threaded filters to lenses with compatible threads or seamlessly adapt Freewell magnetic filters. If you have filters with 72mm rear threads, you can screw them onto lenses with 62mm front threads. Alternatively, for a magnetic attachment, start by screwing this adapter onto a lens with 62mm front threads, and then magnetically affix Freewell's 72mm magnetic filters to the front of this adapter ring.
