About Item

Schneider Circular True-Polarizing Filter (127mm) Listing & For Sale is 1 Brand New Filter in a box with pouch. List Price is $735.00 Stock Code: 68-013127 Availability: In Stock The Schneider Circular True-Polarizing Filter is by far the most effective polarizer 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, and is unmatched in its ability. The polarizing film in a Schneider True-Pol filter is laminated between two pieces of Schneider's crystal-clear, water-white optical glass. The filter is protected against edge-chipping and delamination by Schneider's unique Edge Seal, which also effectively reduces edge-reflections and flare. The absolute clarity of the glass combined with advanced polarizing material make True-Pol filters particularly effective on demanding scenes, as when shooting through windshields in rigged-cars. On such shots, Directors of Photography have found that Schneider True-Pol filters capture more color saturation, wider tonal range and much more contrast inside the car. Like all filters in the Schneider line, True-Pol filters are precision polished to the highest possible standards, meeting the most demanding specifications for optical flatness. Reduce glare and unwanted reflections Saturate colors Deepen blue skies Improve contrast Penetrate haze True-Pol Polarizing filters enable you to achieve a level of optical performance previously unavailable to cinematographers Schneider offers a circular True-Pol Polarizing filter for cameras which use polarizing elements in the beam-splitters of the viewing system, such as ARRI 435 and the Movie-Cam Compact. This filter may also be required on certain high definition video cameras with complex optical blocks such as the Sony PMW-EX1, PMW-EX3, and PDW-700 which polarize the red an blue channels more than other cameras and therefore require a circular polarizer to prevent cross polarization and associated color shift in the image. Beam splitters send light in two directions: to an eye-piece and to a video tap. Light in a camera’s viewing system can become polarized, and when a standard (linear) polarizing filter is attached to the lens, the light becomes cross polarized. This hinders visibility and may create total black-out of the viewing image and/or the video tap. Schneider Circular Polarizers feature a two layer design to prevent this blackout. The first layer is made up of the same polarizing material used in all True-Pol filters; the second layer is a 1/4- wave retarder plate which effectively prevents cross-polarization. High-Quality Construction Schneider solid color filters feature crystal clear, water-white optical glass, protected against edge-chipping and delamination by Schneider's unique Edge Seal, which also significantly reduces edge reflections and flare Schneider Quality Control Schneider filters are ground and polished to a precise flatness and plane parallelism Because all Schneider filters are designed and manufactured with the highest possible degree of consistency, you can swap like filters mid-shoot with no discernible variation in color or effect.

They are also used to reduce glare on car bumpers and to control reflections on plate-glass windows. Polarizers are so versatile that they can perform the opposite functions as well. Some cinematographers use polarizers to increase or enhance reflections, simply by changing the filter’s setting. There is virtually no limit to the new ways Directors of Photography find to use effective polarizers. Virtually any subject involving glare or reflections, or that is illuminated with specular light, can be improved through the skillful use of a quality polarizing filter. What is the difference between a Linear and a Circular Polarizer? A Circular Polarizer is a Linear Polarizer with a 1/ 4 wave plate retarder added to the back of the polarizer foil. Circular Polarizers are necessary when using any camera that has a beam splitter which is used for internal light meter reading or a video tap. The beam splitter polarizes light and depending upon the position of the polarizer, you may cause double polarization and therefore result in inaccurate meter readings, in the case of a video tap a black out. Circular Polarizers are also necessary for auto focus cameras. TIP: In any case in which linear polarizing filters suffice, circular polarizing filters can also be used, but not the other way around. Circular is the best for all situations and worth the extra cost in our opinion. Feedback is very important to us. We would appreciate if you would leave it for us once you have received your item.
