Kase Magnetic Step-Up Ring for Wolverine Magnetic Filters (55 to 82mm)

This steel-made 55 to 82mm Magnetic Step-Up Ring allows you to magnetically attach Kase Wolverine magnetic filters to compatible lenses. The step-up ring screws onto lenses that have a 55mm front filter thread, and your 82mm Wolverine filter then magnetically attaches onto the ring and is just as easily removed.
