A versatile 77mm NDX fader that provides continuous neutral density control from ND2 - ND1000. The filter uses multicoated glass construction to preserve image quality across a wide range of lighting conditions. Rather than swapping or stacking filters, simply turn its exterior ring to select any neutral density setting, allowing you to dial in the exact amount of attenuation scene to scene and save time when changing setups.
