Formatt Hitech ND Filter (150 x 150mm, 7-Stop)

This 7-stop, 150 x 150mm Formatt Hitech ND Filter is a neutral density filter that provides a 1-stop exposure reduction and is compatible with a For LEE SW150-Series filter holder. Its 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required.
