Product Description
This B+W ND filter, which reduces light entering the camera by six f-stops,
already qualifies as an extreme filter. With this filter, and without changing
the aperture (and DOF), an exposure time of 1/60 s becomes a full second.
Running water is rendered hazy and soft. A tripod is necessary in any case.
The excellent finely ground and polished special glass is used as the basis for
the new ND filter glasses. This guarantees the necessary optical quality and
also does not have any adverse effect on a correspondingly high-quality lens.
With the thin-film technology developed here, not only the pure ND filter effect
comes into play, but a coating combination optimizes the ND filter. In addition
to the filter effect, the coating combination contains a multi-layer
anti-reflective component with 7 layers per filter side to prevent annoying
reflections. An outer layer with the usual dirt- and water-repellent properties
is applied as the final layer. This not only provides all-around protection for
the filter, but also makes it easy to clean and maintain the filter pane. The
light attenuation itself is very uniform over the entire visible range and
produces optimally color-neutral image results.
