Expand the range of creative effects available to you with the PowerND ND4000 37mm ND 3.6 Filter from Aurora-Aperture. This round 3.6 ND filter features a 4000x filter factor that provides a 12-stop reduction in exposure, allowing you to slow down shutter speeds to a few seconds under daylight or minutes during dusk and dawn. It also lets you use wider apertures in bright lighting situations, or combine wide apertures and slow shutter speeds with ease.
Applied to both sides of the glass, the filter's multi-layer nano coating allows for accurate color performance and little to no loss in resolution. This coating also repels water, oil, and dust to make the filter surface easy to clean. The PowerND is made of SCHOTT B 270 glass for increased clarity and durability and has a slim profile with a thickness of 3.4mm that minimizes vignetting when using wide angle lenses. Finally, 37mm front filter threads enable stacking with other filters to achieve a wide variety of effects.
