Please note: This filter does not include a magnetic adapter ring. The UV filter screws directly into your lens and features a magnetic connection on the outer side of the filter, allowing you to attach magnetic filters directly to the UV filter.
The UV filter also functions as a Kase Magnetic Lens Adapter Ring that allows nonthreaded Kase Wolverine magnetic filters to be used on a lens with 112mm front filter threads. Its rear-threaded filter ring is constructed from steel and allows for the convenient installation or removal of nonthreaded Kase Wolverine magnetic filters. With a Kase Magnetic Lens Adapter Ring, up to four Kase Wolverine magnetic filters can be magnetically stacked in front of a camera lens.
