The 52mm Kase KW Revolution Entry Kit 52mmfeatures ND8, ND64, and CPL magnetic filters as part of Kase's color-coded KW Revolution filter system. The filters are designed with color-coded filter frames for easy identification and swapping. The ND8 is color-coded blue, the ND64 is yellow, and the CPL is silver. The kit also includes adapter rings, a filter case, and a front lens cap. The KW Revolution system is based on Kase's earlier Wolverine series and is fully backwards-compatible with Wolverine filters.

KW Revolution filters are made with shock resistant and water resistant optical glass that's durable, easy to clean, and doesn't cause any color cast. In addition to being magnetic, the filters are also front threaded. This is one of the differences between the KW Revolution series and the earlier Wolverine series.

This kit includes both the standard magnetic adapter and the inlaid magnetic adapter supported by the KW Revolution series. The standard adapter screws onto your lens and lets you magnetically attach the filter to it. The inlaid adapter works a bit differently, as it secures to your lens in a very recessed way. It screws onto the front filter threads very close to the front lens element and remains nearly hidden within the filter thread area. It hardly leaves any space between the lens and filter. This results in minimized vignetting with wide-angle lenses when you attach the filter. The filter snaps onto the adapter magnetically. Up to four filters can be stacked in total, both from this KW Revolution series and from the earlier Wolverine series, and the filters can be freely rotated. Please see more about the inlaid adapter below.

When your KW Revolution filter (or backwards-compatible Wolverine filter) is removed from the inlaid adapter, you can leave the adapter on the lens. It will not interfere with attaching the original lens cap to the front of your lens. Similarly, it won't interfere with screwing in regular screw-in filters to the filter threads of the lens.

Besides securing directly to the lens, the inlaid adapter can instead be screwed onto the front threads of regular screw-in filters. The screw-in filter can then be screwed onto your lens, and the inlaid adapter will be on the front of that filter. You can then magnetically attach KW Revolution and Wolverine filters onto the adapter. The benefit of this flexibility is that it allows you to mount the KW Revolution filters on top of regular screw-in filters that you may want at the bottom of your stack.

The inlaid adapter is not compatible with step rings.

There are a few ways to screw in the ultra-slim inlaid adapter. The main way is to first attach it magnetically to one of the included ND filters, and to then screw in both by hand. Then you can remove the filter or stack additional ones onto it. You can also attach the optional Kase magnetic lens hood.
