Product Highlights
  • Minimize Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Enhances Color and Tonal Saturation
  • 4mm-Thick Glass Construction

The Cavision 4 x 4" Linear Polarizer Filter helps to 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.

This filter measures 4 x 4" / 101.6 x 101.6mm and is constructed from 4mm-thick optical glass.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
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° angle from the sun.
Constructed from high quality optical glass.
Type Linear polarizer
Size 4 x 4" / 101.6 x 101.6 mm (4 mm thick)
Filter Factor About 2.5 (1.3 stops)

      You need this!

      Polarizing filters obviously are useful when shooting thru a window. But a polarizer can control all sorts of subtle highlights on faces, leaves, almost any surface.

            - It's a great filter without any color shift when compared to shutter speed matched footage on my DSLR.- The glass is solid and doesn't feel cheap.

              If glass filters is what you need, look no further that Cavision. Their selection of glass filters for a matte box is the best. I only use Cavision for all my filter needs.

                We bought this because we needed a linear pola for use in our matte box for some pro work. It came in, and we were happy. The glass doesn't .... Feel flimsy like some others we've handled. The unit has a black cover, for lack of a better word, all the way around it on the edge. It keeps you from touching the glass itself.

                It works, however... Do not buy this if you do not have a 4x4 mounting system in your camera, you will not be able to use it without accessories.

                      Recently purchased a Matte Box and noticed that most square filters were expensive. This is a great product from a reputable company. Also a GREAT PRICE so I can test the filter assembly of my Matte Box.

                      I plan to shoot reflective surfaces and this is a MUST!

                          I have only used this filter a few times so far but it seems to be no different then some of the more expensive filters I have used it the past. Also, not mentioned under "Item Includes", this filter comes in it's own case wrapped in a cleaning cloth. Excellent buy.

                              Great filter at a very reasonable price. This seemed to work as effectively as more expensive polas, and comes with a great little case and cleaning cloth. I wasn't expecting that for the price.
