NiSi Filter Circular For S6 ND32000 (15Stop)

The NiSi circular ND32000 (15 stop) filter is designed for use with the NiSi S6 150mm filter holder system and provides a 15-stop exposure reduction. It can screw into a NiSi S6 150mm filter holder adapter ring after the kit's included Pro Screw-In Circular Polarizer Filter has been removed. A density of 4.5 darkens the entire image, allowing a wider aperture or slower shutter speed and easier control of depth of field and movement. Such a filter is widely used for extreme long exposures (usually 3-6 minutes in daylight), for example to capture cloud movement.

NiSi ND filters do not affect the coloration of the image and are made from high-quality optical glass (not resin) with nano coating. An infrared protection layer eliminates unwanted red color casts, and the NiSi Pro Nano Coating reduces reflections and is waterproof and scratch-resistant.
