Engineered for the Sigma Normal 50mm f/1.4 EX DG HSM, this 77mm NDX variable neutral density fader offers comprehensive exposure control. Adjustable from ND2 - ND1000, it lets you reduce light precisely to suit any shooting condition. The multicoated glass construction preserves image quality and minimizes reflections. Density is changed by rotating the exterior ring, so you can select any setting in the ND2 - ND1000 range without swapping filters—saving time when lighting changes. The variable neutral density design enables fine, scene-to-scene adjustment of light reduction.
