Exposure Done Right. The LEE 150 × 150mm SW150 Little Stopper 1.8 ND Filter is a neutral density filter with a 64x filter factor that provides 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters. With the compatible & separately rented LEE SW150 Mark II Filter System Holder for Wide-Angle Lenses, you’re able to stack 2 filters 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.
