About Tiffen 138mm Filter
138mm Variable ND
Tiffen's patent pending 138mm rear matte box mounted Variable ND donut is a unique, versatile and flexible tool, affording you the convenience of using several Neutral Density filters in one unit. Primarily used as a photographic tool for controlling depth of field and exposure, the Variable ND concept of light control has migrated into the moving digital image market, due to its speed andease of use. Designed to fit into the rear 143mm port of a bar mounted matte box, which is compatible by a wide variety of matte box manufacturers. This rear location is a perfect spot to place the unit, as the 138 VND requires a smooth surface to rotate within.
