Exposure Done Right. The LEE 150 × 150mm SW150 Super Stopper 4.5 ND Filter is a neutral density filter with a 32,000x filter factor that provides a 15 stop exposure reduction. Its density sits at 4.5, allowing the image to darken and to photograph with a wider aperture or slower shutter speed than normally required without affecting the coloration of the image. These filters are ideal for stacking, and with the separately-rented LEE SW150 Mark II Filter System Holder you’re able to stack 2 at a time.

Built For Greatness. Curated from optical glass, this filter offers incredible clarity, does not affect coloration of the image, and is ideally used with other filters. The included metal filter case makes for easy & safe storage and transport.
