The SW150 Mark II filter holder comes assembled with two filter slots and includes the SW150 Lightshield, enabling you to use neutral density graduated filters in combination with other filters. The included lightshield helps to prevent unwanted back reflections and creates a light tight seal enabling the use of Big Stopper.
The LEE Stoppers are solid ND filters that allow you to increase the exposure in your images, rendering clouds soft, water smooth and milky, car headlights as streaks of color, or people as abstract, blurred figures. The Little Stopper is a 6-stop ND 1.8 filter that is ideal for low-light conditions, such as dawn or dusk. The Big Stopper is a 10-stop ND 3.0 filter that allows for longer exposures and is ideal for the midday setting when the sun is brightest.
