Tiffen 4.5" Round Ultra Polarizer Linear WW (DI) Filters offer the best polarization effects available for professional motion picture and television work. They extract the maximum of unwanted glare from the scene and render crisp white clouds against a dramatically dark blue sky, like never before. Distracting reflections from water and windows become invisible with the magic of the Ultra Pol filter.
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 and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4.5" / 114.3mm in diameter and is mounted within a metal ring. 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.
They are available in our wide array of sizes and require 1-2/3 stop exposure compensation.
Tiffen precision crafted filters are the overwhelming choice of film and video professionals around the world. their superior quality is backed by the Tiffen ten-year warranty.
