The Tiffen 138mm Double Fog 1/2 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 1/2 density provides a small 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: 10. Hi,I own the Bright Tangerine Misfit Atom. I only see the Misfit in the compatibility list. Do you know if it will work? Thanks

A: Sorry, but the Tiffen 138mm Variable ND in Matte Box Mountable Rubber Donut for 143mm Openings is too big. The front, the part that mates with the matte box holds is 143mm so it can hold the 138mm filter. This means it is bigger than the rear of the Misfit Atom which takes a maximum of 114mm. To do what you wish, you may have to go with a screw in 114mm filter or another matte box.
