Sirui 77mm Nano Multi-Layer Coating Variable Neutral Density Filter (1 to 8-Stops)

Long exposure tool with exceptional polarized color.
ND Filter is a Neutral Density Filter. When shooting in the bright sun or in strong light conditions, and the shutter speed needs to be slowed to create brilliant effects, the ND filter is a great tool. It reduces the light entering the camera to increase the aperture and adjust the shutter to maximize the creative control of the image.

The Variable ND Filter can adjust the neutral density effect by turning the outer ring from 1 to 8-stops. It can help with the use of larger apertures to control motion blur, depth of field and other special effects to maximum your shooting experience.
