The new B+W ND 800 filters
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.
In the thin-film technology that has been developed here, it is not just the pure ND filter effect that delivers results: a combination of coating optimizes the ND filter. In addition to the filter effect, the combination coating also prevents troublesome reflections by including a multilayer anti-reflection component with seven layers on each side of the filter. Finally, an outer layer with the usual dirt- and water-repellent properties is applied. With this feature, the filter not only has all-round protection, but simple cleaning and care of the filter disk are also taken care of.
The light attenuation itself is very uniform over the entire visible range and therefore produces optimal, color-neutral images. By being able to use this coating technology at specified glass substrates, the process can also be applied in the B+W XS-Pro digital filter range.
XS- digital filter range.
This B+W ND filter reduces the light by three f-stops and is particularly interesting for video when no suitable aperture can be selected in bright light or when a specific, small DOF is required. With this filter, distinct flow of water effect becomes apparent. The B+W 103 ND filter 0.9 is also ideal for shooting photos with a wipe effect.
