77mm NDX Variable Neutral Density Fader Filter — Adjustable ND2 - ND1000 for Tamron 70-200mm f/2.8 Di LD (IF) Macro

A 77mm NDX variable neutral density fader that gives you flexible exposure control, adjustable from ND2 - ND1000. The multicoated glass construction preserves image quality while minimizing unwanted reflections. Instead of swapping or stacking filters, simply rotate the outer control ring to choose any neutral density setting on the fly. This saves time during shoots and lets you quickly dial in the exact amount of density needed from scene to scene for motion blur, depth-of-field control, or balanced exposures in bright conditions.
