The Tiffen 86mm Double Fog 1/8 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 1/8 density provides the least amount of fog effect and requires no exposure compensation.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 5. will this filter work on a televue 85 scope and not affect sharp focusing of nature subjects ?

A: It would be almost impossible for this filter to affect sharpness. Your light is already traveling through huge amounts of glass. The idea that one tiny extra layer will make any difference is simply wrong-headed, yet many "pros" will tell you they never want to add another layer of glass. This is especially wrong when dealing with B+W, whose glass is made by Schott. Schott in Germany and Hoya in Japan make the finest laser optical glass in the world. It will be virtually perfect in every regard.
