This Kase Wolverine Magnetic ND Filter Kit for Canon EOS-Rfrom Kase Wolverine Magnetic ND Filter Kit for Canon EOS-Ris a filter holder designed to fit the Canon EOS-EF to EOS-RF lens adapter. This magnetic filter holder replaces the drop-in filter holder that comes with the lens adapter. It includes a 3-stop neutral density filter to increase the exposure over the entire image area. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase motion blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background.

The filter is made from hardened, shockproof optical glass that features layers of multicoating for reduced glare and optimal light transmission. It also features a resistance coating on each optical surface that resists water, oil, dust, fingerprints, and scratches, making it easy to clean. This filter kit includes a leatherette storage case with a magnetic clasp.
