The 52mm Sion Solid Neutral Density 0.6 Filter from Vu Filters is an ND filter with a 4x filter factor that provides a 2 stop exposure reduction. Its 0.6 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
To prevent internal ghosting and reflections, each glass surface includes seven layers of anti-reflection coating. This multi-coating also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Flat Wave Overcoat associated with this Sion solid neutral density filter provides an additional eighth layer over the multi-coatings on the front side of the filter, resulting in an improved beading effect to repel water for greater cleaning efficiency.
This Sion solid neutral density filter is constructed from Schott glass for optical clarity as well as color fidelity and features an aluminum-alloy filter ring for durability while remaining lightweight.
