The non-rotating Tiffen 138mm Ultra Pol Linear Polarizer Filterhelps to greatly reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

There is a total filter factor of about 4, requiring an increase of 2 stops for normal exposure. This filter is constructed from Water White glass and 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. The non-rotating design of this filter is best-suited for use with lens hoods, adapters, or other rings for rotational control over the polarizing substrate.

Compared to a standard polarizer, the Ultra Pol design strives to increase the polarizing effect for enhanced reduction of reflections and greater color saturation.

Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° from the sun.

Water White optical glass for excellent clarity.

Non-rotating design is best-suited to use with lens hoods or adapter rings in order to best control the polarizing effect of the filter.

Q: 8. Will this work with the Bright Tangerine Misfit Atom Pola+ Matte Box?

A: Yes it will.

Q: 9. Does rotating the filter change it’s effect?

A: Yes, you insert the filter in a holder and rotate the holder to achieve the desired effect, ie; removing reflections from glass or water as well as saturating colors, etc...

Q: 10. Will this filter work with RotaPola Rota-Tray 4x5.65" ?

A: No, it is not compatible.
