The Big Stopper 3.0 Neutral Density Filter from LEE Filters is an 85 x 85mm solid neutral density filter, which provides a 10-stop reduction in exposure. This 3.0 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.
This filter is constructed from a high-quality optical glass for high definition and clarity. It is compatible with the LEE85 Filter System, which is designed for use with compact cameras, mirrorless cameras, and mirrorless lenses. This filter measures 3.5 x 3.5" / 85 x 85mm.
