Mounted within a nonthreaded filter ring, the Kase Wolverine Magnetic ND32,000 Solid Neutral Density 4.5 Filter is made specifically to fit within a Kase Magnetic Lens Adapter Ring for Wolverine Magnetic Filters. Each surface of the filter's tempered, shock-resistant optical glass includes multiple layers of anti-reflection coatings to prevent internal ghosting and reflections while further enhancing clarity as well as color fidelity. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
The included magnetic lens adapter ring allows a Kase Wolverine magnetic filter to be used on a lens with 77mm front filter threads. It is constructed from steel and allows for the convenient installation or removal of that filter.
