72mm NDX Variable Neutral Density Fader (ND2 - ND1000) for Sigma SD15

72mm NDX variable neutral density fader designed for the Sigma SD15, offering an adjustable range from ND2 to ND1000. The glass elements feature multi-coated construction to help preserve contrast and reduce flare while you control exposure. Density is set quickly and precisely by rotating the filter’s outer ring, so you can fine-tune light reduction without swapping glass. Ideal for saving time on location, this variable ND lets you dial in differing amounts of attenuation from scene to scene.
