Formatt Hitech 82mm Multistop and Warm2Cool Filter Kit

The Hitech 82mm Multistop and Warm2Cool Filter Kit includes both the Multistop variable neutral density filter and the Warm2Cool variable color filter. The Multistop filter provides a reduction of about 1 to 6 stops of exposure with a density range of 0.3 to 1.8. The Warm2Cool filter offers a range of color possibilities from cooling blues to warming yellows. Both filters have a large front rotating element to reduce vignetting when used with wide angle lenses. They are constructed from CR-39 resin between two layers of Schott glass and feature aluminum filter rings.
