Helping to reduce the overall exposure by four stops, this 67mm ND 16x Filter from Leica is a solid neutral density 1.2 filter offering greater control over exposures. The solid ND 1.2 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 can control depth of field and convey movement more easily.
The filter is constructed from optical glass and set in lightweight aluminum rings; both are of the same standards as those used in Leica's M lenses. The glass has also been multicoated to help suppress flare and ghosting for improved contrast and color accuracy.
