Formatt Hitech ND Filter (165 x 165mm, 4-Stop)

This 4-stop, 165 x 165mm Formatt Hitech ND Filter is a neutral density filter that provides a 4-stop exposure reduction and is compatible with a Lucroit 165mm Pro Filter Holders. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required.
