The 49mm Kase Wolverine Magnetic ND Filter 49mm, 1.5-10 Stop, Gen 2from Kase Wolverine Magnetic ND Filter 49mm, 1.5-10 Stop, Gen 2provides an increase in neutral density through a 1.5 to 10-stop range. 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 and increasing bokeh.

The filter is made from a durable tempered optical glass that is shockproof and almost indestructible. It features multicoated surfaces for reduced lens glare, providing optimal light and color transmission. The rotating magnetic aluminum filter ring has a density scale for repeatable results. The included adapter ring fits on 49mm lens filter threads, and the front of the filter allows slightly larger 52mm-size magnetic filters to be stacked on, to add additional filter functionality without vignetting. It is fully compatible with Kase Wolverine, Kase Revolution, and Kase Skyeye magnetic filters and lens caps.
