Formatt Hitech 105mm HD Combination Hot Mirror/ND 1.8 Glass Filter (6-Stop)

The Formatt Hitech 105mm HD Combination Hot Mirror/ND 1.8 Filter was created to deal and correct with infrared "noise". Today's digital cameras, with their ultra-sensitive sensors, are particularly susceptible to infrared contamination. This issue becomes magnified when using high density ND filters. This filter, with its steep cut-off of infrared light, allows a more natural picture without interfering with the red end of the spectrum.
