138mm Wormhole

The 138mm Wormhole is a spiral cut specialty filter with a 52mm polished flat window in the center. This filter creates a zooming or stretch effect where the edges of the frame have streaks of light and distortion similar to a still photo zoom rack. This filter is the thickness of a +3 diopter and weighs over 1 lb (500 grams). We recommend the Atlas 138mm-114mm holder or the Vocas 5-Axis Diopter Holder. You can also use 138mm rear donut holders. The Bright Tangerine One Tray or Revar Cine Double Tray are not compatible as the filter is thicker than the tray depth.
