Tiffen Series 9 85 and Neutral Density Drop-in Combination Filter :
Several filter combinations are so popular that they are produced as two filter effects in one. These include: Neutral Density or Polarizer plus 81 or 85 Wrattenﾮ filters; and the Polarizer plus the ENHANCING filter.
This filter is a combination of a neutral density, and a 85 color conversion filter all in one. Available in density rating of 0.3, 0.6, 0.9 and 1.2, this filter eliminates the need to buy two filters and frees space for filter placement at the same time.
