110 77mm 3.0 ND 1000x
Neutral Density Filter
With a light intensity reduction of ten f-stops, this B+W Neutral Density Filter has a slightly stronger warm tone than the ND 106. It is designed to reduce all different wavelengths of light for an even 10 stop reduction in light. This allows your shutter speed to be slowed significantly, which is particularly useful when photographing water and tides, or when a dramatic effect is desired. The filter factor is 1000x.
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%.
This filter uses the standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass. 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.
