Tiffen showed off a few interesting filter products at NAB, including a new 138mm variable ND, and the new Rota Pola VND, which takes their circular polarizer filter tray, and adds another polarizer to give you a variable ND:

To read more on the 138mm, there's a PDF you can check out here. Here's more on the Rota Pola VND (which doesn't seem like it's shipping yet but should retail for under $1,000):

  • Up to three effects in one unit:
  1. Rotating Tiffen 138mm Circular Polarizer
  2. VND (Variable Neutral Density)*
  3. Warm to Cool FX fader*
  • Geared 138mm Tiffen ultra-thin polarizer for greater field of view
