LEE Filters – Little Stopper, 100×100 Glass, 6 Stop
The LEE Little Stopper is a neutral density filter made from optical glass that reduces the amount of light entering the lens to enable long shutter speeds. It is available for the 100mm, SW150 and Seven5 systems. It is packaged in a protective tin case and carries a lifetime warranty. LEE filters states that “the filter has a slight color cast” that it claims is easy to remove in post-production. The Lee Little Stopper reduces the light by 6 stops with a filter factor of 64, and has a density of 1.8, meaning a regular two-second exposure would calculate to a 2 minute exposure.
