Vu Filters 55mm Sion Neutral Density Filter

The 55mm Sion  Neutral Density Filter from Vu Filters is a solid ND filter providing a 1-stop reduction in exposure. This 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.

Further enhancing image quality is a White Balanced Multi-Coating that ensures that there is little to no color shift. Also, a Flat Wave Coating makes the filter's front surface exceptionally smooth for easier cleaning and maintenance.

This filter is hand crafted and individually inspected for ensuring quality and uses German-formulated ionic dispersion optics for maximum performance. The glass edge is black to prevent internal reflections
