Formatt Hitech 48mm HD Combination Hot Mirror/ND 1.2 Filter (4-Stop)

The Formatt Hitech 48mm HD Combination Hot Mirror/ND 1.2 Filter has been specially formulated resulting from extensive research into the applications of molecular A.C.T. dyes (Absorption Cell Technology). This unique filter gives more of a neutral gray look without the specular effects that you see in current neutral density and graduated neutral density filters - thereby allowing you more precise control.
