Lee Filters is adding a new neutral density filer to it’s lineup called the Super Stopper. The Super Stopper limits the amount of light that hits your camera’s sensor by 15 stops, meaning that an ordinary 2-second exposure would take over 17 hours to expose through the filer.
The new Super Stopper filter joins the Little Stopper (6 stops of light) and Big Stopper (10 stops of light) in the Lee Filters group of long-exposure ND filters. The Super Stopper will be available for the 100mm, Seven5, and SW150 lines of Lee Filters products.
“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,” Lee Filters’ press release says. “However, with the Super Stopper filter fitted, the softness that arises from any movement contrasts pleasingly with any areas of bright light, creative an effect rarely seen in photography before now.”
Here’s a chart that shows how long exposures can be stretched with the Super Stopper filter.
According to DPReview, the filters in the SW150 series will cost $175.
