Tiffen 138VNDMATTEBOXMNT - 138MM REAR MATTEBOX MOUNT VARIABLE ND DONUT

Tiffen's 138mm Variable ND in Matte Box Mountable Rubber Donut for 143mm Openings provides approxiately 6-stops of variable nuetral density control without taking up any filter tray space. The variable ND is incorporated within a rubber donut that fits into a wide variety of matte boxes with a 143mm rear opening. It features a minimum of 2- and a maximum of 8-stops of light attenuation.

The variable ND has no impact on the field of view that a standard donut that accepts a 138mm filter has, so there is no change to your workflow or shooting style. It features evenly spaced index marks from 2- to 8-stops, but these are not calibrated marks and do not indicate amount of attenuation. A 114mm threaded rear ring accepts ARRI R2 compatible threaded reduction rings. The rubber donut is compatible with matte boxes from ARRI, Tilta, Movcam, Vocas, and Bright Tangerine.
