B+W Neutral Density (ND) 3.0 110 Filter

Filter Size: 77mm

Made In Germany

Note: Above pictures  are just for reference. The real filter size pls check the title!!!

This filter is  made in Germany using high quality Schneider optical glass held in  place by heavy duty brass rings, these filters are the epitome of quality;  It is useful for the observation  and documentation of industrial processes with extreme brightness, such as  steel furnaces, incinerators, glowing filaments in halogen- and other bulbs;  It prevents strong flare and brings out interesting details.

Especially,  it is 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!

Newly-improved F-Pro mount

1. Maintain the excellent  quality of materials, fabrication, and high mechanical  stability;

2. Become thinner, so that  now it can also be used on many wide-angle lenses without the  danger of vignetting. 

3. Modified retaining ring,  which is no longer threaded in from the front, but holds the  filter glass in place from the back.  This prevents the  retaining ring from being accidentally loosened during the  removal of an additional filter or a lens hood that has been  screwed in too tightly.

They have no effect on color balance. They have four main uses:

1) To  enable slow shutter speeds to be used, especially with high  speed films, to record movement in subjects such as waterfalls,  clouds, or cars.

2) To  decrease depth of field by allowing wider apertures to be used,  which helps separate subjects from their background.

3) To  decrease the effective ISO of high speed film (above ISO 400)  and allow it to be used outdoors in bright situations.

4) To  allow cine and video cameras (which have fixed shutter speeds)  to film subjects such as snow, sand or other bright scenes，which  could cause overexposure. These filters are available in  increments from one stop to twenty stops exposure reduction.
