The KW Revolution Magnetic ND1000 Solid Neutral Density 3.0 Filter is an ND filter with an 1000x filter factor that provides a 10-stop exposure reduction. An included Kase magnetic lens adapter ring allows the filter to be used on a lens with 82mm front filter threads. The filter's 3.0 density creates a darkening of an entire image without affecting the image's coloration, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you can control depth of field and convey movement more easily.
Each surface of the filter's optical glass includes multiple layers of anti-reflection coatings to prevent internal ghosting and reflections while further enhancing clarity as well as color fidelity. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
The KW Revolution line of filters from Kase are color-coded for quick and easy identification and feature front threads allowing them to be compatible with a wide range of filters and accessories.
