The NiSi Cinema Rotating 77mm Allure Streak Orange (2mm) is a special effect filter that reproduces a single beam of light from a point light source. This filter features a series of etched lines that run 2 mm apart across the filter surface. The filter creates the effect of elongated orange streaks that radiate horizontally from the light source, typically seen when using an anamorphic lens. The 77mm filter has a rotating front that allows you to adjust the orientation of the light beam to fit the composition or desired effect. The filter is made from clear optical glass H-K9L for consistent image clarity and has an aluminum frame.
