• Polarizers are two part lenses that rotate, allowing you to select the degree of additional saturation, contrast and glare reduction desired.

  • Gives the same deep contrast and glare reducing properties to black and white photography.
  • Combines with Red filters for incredibly dramatic landcsapes.

Works as Described


from Mahopac, New York  -  Photo Enthusiast

This polarizing filter does exactly what it should. It reduces reflections and slightly increases saturation. It works best with a matte box and won't fit certain on-lens filter holders due to its thickness. I tested it using a Canon 600d (T3i) with various Canon, Sigma, and Tamron lenses with a Proaim V11 mattebox.

Works, But Won't Fit Lee Holder


from Boston, MA  -  Photo Enthusiast

The filter glass is clear and packaged well. Although it works as described to polarize light, the filter is too thick to fit the Lee Foundation filter holder .

Questions about this item:

Ken B  Can linear polarizers work on DSLR's or do I need a Circular one? Thanks Ken
EDWARD H  It depends, Linear will work... but it may effect auto focus and meter readings and run the risk of exposure errors (+/- 1 stop). In general; if you are manually focusing and exposing for video and checking your exposure through a monitor, the liner is fine. if you are planing on using auto focus and auto exposure you will need a circular.
