77mm NDX Variable Neutral Density Fader Filter — Adjustable ND2 - ND1000 for Canon EF 16-35mm f/4L is USM

Take precise exposure control without swapping filter stacks. This 77mm NDX variable neutral density fader spans ND2 - ND1000, allowing gradual light reduction for bright conditions or creative long exposures. Its multicoated glass construction helps preserve contrast and minimize reflections and flare while maintaining image quality. Density selection is quick and simple — just rotate the exterior ring to choose any setting within the range — so you can save time compared to adding or removing fixed filters. Built for changing scenes, the variable ND lets you dial in exact amounts of attenuation to match the lighting on the fly.
