Tiffen 4.5" Warm Circular Polarizer Water White Glass Filter. This is a wonderful filter designed to bring significantly more "snap" to your images. If a traditional polarizer doesn't give you enough "zip", the "Ultra" polarizer gives you a little more. It will bump up your blue skies even more - making the difference between a good photo and a great image.
The additional warmth that this filter generates comes from the incorporation of Tiffen's exclusive 812 Warming filter.
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).
What is the differences between this model and http://www.bhphotovideo.com/c/product/398871-REG/Schneider_68013038_138_mm_True_Linear_Polarizing.htmlIt seems like its just different descriptions but the same product. The only noticeable difference is a 10 year warranty on the more expensive model. What exactly does this cover? Does it cover it breaking?

Basically, there are two types of Polarizing filters; Linear and Circular. Linear are used for manual focusing as they can confuse AF sensors. Circular filters are designed for AF lenses and cameras but can be used on manual focus cameras as well. For more details on the two, please see: http://bhpho.to/MF21zoThe Schneider 138mm True-Linear Polarizing Glass filter is optimized for motion picture and television cameras. Having an extinction ratio of ER 374, the Schneider True-Pol is 12-times more effective than other polarizing filters. The 138mm Circular Ultra Polarizing Filter from Tiffen is a similar filter yielding a more intense look to your images and is designed for AF cameras. Because of manufacturing differences, circular polarizing filters cost more than comparable linear filters. Both filters come with ten year warranties that cover manufacturing or workmanship defects.

Will I need to buy any kind of rotating adapter to drop this in? I have a matte box (on order) that states: 2 universal 360 degree rotating filter stages + 2 filter trays that support both 4x4 and 4x5.65 filter sizes
Asked by: Rob L.
Which matte box did you purchase? Does it accept 138mm filters?
