B+W 77mm ND8 (0.9) 3-stops 8X Neutral Density ND Filter (103E) #73102 (Made in Germany)

The Schneider Group in Germany specializes in developing and producing high-performance photographic lenses, cinema projection lenses, as well as industrial optics and precision mechanics.  B+W brand photographic filters are established as premium products in the trade worldwide since 1913.

This B+W Neutral Density Filter reduces the light intensity by three f-stops (log density 0.9). It still features very good color neutrality. This ND filter is especially appropriate for use on video cameras when the lens cannot be stopped down sufficiently in great brightness or when a deliberately low depth of field is desired. The filter factor is 8x.

Filter Coating

Single Coating

Each glass surface is vacuum coated with one layer of Anti-Reflection coating. This single layer helps to prevent internal ghosting and reflections. It also improves light transmission from approximately 92% (uncoated glass) to over 98%.

Mount

This filter uses our standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass. Compared to the earlier standard mount introduced in 2001, the F-Pro mount has become thinner. Now it can be used with wide angle lenses, including most 24mm focal lengths on a full frame body, without vignetting. Another advantage of the F-Pro mount is it's modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. When removing a filter or lens hood that has been screwed on too tight to the filter, the retaining ring is not at risk of loosening.

NOTE: diopters are mounted in the older mount due to glass thickness.
