72mm NDX Variable Neutral Density Fader Filter Adjustable ND2 - ND1000 for Sony 135mm f/2.8

A flexible variable neutral density fader that gives photographers precise exposure control without swapping glass. This 72mm NDX filter continuously adjusts from ND2 - ND1000—simply rotate the exterior ring to select the exact density you need for any scene. Constructed with multicoated glass to reduce reflections and preserve image quality, it replaces the need to add or change multiple fixed ND filters and speeds setup in changing light. Ideal for use with the Sony 135mm f/2.8, it lets you quickly dial in varying amounts of light reduction frame to frame.
