77mm NDX Variable Neutral Density Fader Filter (ND2 - ND1000) for Pentax K100D

A 77mm NDX variable neutral density fader that covers an adjustable range from ND2 to ND1000, letting you control exposure seamlessly without swapping glass. The filter's multicoated glass construction reduces reflections and preserves image quality across settings. Quickly change the amount of density by rotating the exterior control ring to any position between ND2 and ND1000 — perfect for adapting to shifting light and scene conditions. This design saves time compared with adding or changing individual filters, since you can dial in varying densities scene to scene.
