67mm NDX Variable Neutral Density Fader Filter (Adjustable ND2 - ND1000) for Pentax SMCP-DA 16-45mm f/4.0 ED AL

Built with multicoated glass, this 67mm NDX variable neutral density fader lets you control exposure across a wide range of lighting situations. The filter’s density is continuously adjustable from ND2 - ND1000 by twisting the outer ring, so you can set the exact attenuation you need without changing glass. Eliminates the time and hassle of swapping or stacking fixed ND filters and makes it easy to dial in different density levels from scene to scene.
