Urth Variable ND Lens Filter Plus+ (46mm, 3 to 7-Stop)

This 46mm Variable ND Lens Filter Plus+ from Urth provides an increase in neutral density through a range from 3 to 7-stops. 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. This level of image control can help to create more cinematic effects in low to bright light.
