H&Y Filters Swift Magnetic VND Filter (1.5 to 5 Stops)

This Swift Magnetic VND Filter (1.5 to 5 Stops) from H&Y Filters is built to connect the A Base Modules and C Accessories in Swift Magnetic System. This precision-crafted variable ND filter is made to avoid cross-polarization issues. The filter is built with a magnetic mount that is compatible with Drop-in Filters or with accessories like the Magnetic Matte Box, Magnetic Square Filter Holder, and Magnetic Collapsible Lens Hood. Simply clip the VND onto the RevoRing base to use it on lenses with different filter sizes. It is designed with an end-stop and a control handle.

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 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.
