Lee Filters has announced it is to offer a neutral density filter that converts what would normally be a two-second exposure into one that lasts 17 hours and 4 minutes. The new Super Stopper reduces the amount of light entering the lens by a massive 15 stops, to enable especially long shutter speeds in normal daylight conditions.

Available for the 100mm, SW150 and Sev5n ranges, the filter is made from what Lee describes as 'high-quality optical glass'. It comes packaged in a protective tin case and has a lifetime warranty. The company says the filter induces only a slight color cast that it claims is easy to remove in post-production. It joins the 10-stop Big Stopper and the 6-stop Little Stopper in the company’s range of ND filters.

The filter factor of the Super Stopper is 3200 and it has a density of 4.5. It will be available soon, and the version for the SW150 series will cost $175. For more information on the company see the Lee Filters website – though the company hasn’t posted any details of the Super Stopper yet. There is more information though on the website of UK distributor, Linhof Studio.

Press release:

LEE Filters NEW Super Stopper Available for 100mm, SW150 and Sev5n.

With its 15 stops of light-reducing power, the Super Stopper sits at the top of the Stopper family, joining the Big and Little Stoppers in the long-exposure photography revolution.

The Super Stopper is designed for use in bright conditions, during the middle of the day – a time that’s traditionally considered unsuitable for photography because of the harsh, contrasty nature of the light.
However, with the Super Stopper filter fitted, the softness that arises from any movement contrasts pleasingly with any areas of bright light, creating an effect rarely seen in photography before now.

Like all the filters in the Stopper family, the Super Stopper is constructed from the high-quality optical glass and is supplied in a metal case for protection. It has only a minimal colour cast that is easily corrected in postproduction.
