The ND64 solid neutral density 1.8 filter is an ND filter with a 64x filter factor that provides a 6-stop exposure reduction. An included Kase magnetic lens adapter ring allows the filter to be used on a lens with 77mm front filter threads. The filter's 1.8 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.
The circular polarizer filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
Each surface of the filter's tempered, shock-resistant 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.
