NDX 77mm Variable Neutral Density Fader Filter — Adjustable ND2 - ND1000 for Sony Alpha DSLR-A200

Compact variable neutral density fader that gives you full exposure control without swapping glass. The filter’s multicoated glass construction maintains image quality while letting you smoothly set any density between ND2 - ND1000 by rotating the outer ring. Ideal for changing light conditions, it lets you fine-tune attenuation scene-to-scene and saves time versus adding or replacing individual ND filters.
