The Tiffen 5.65 x 5.65" Ultra Pol Linear Polarising Filter can significantly reduce reflections and glare by filtering directionally polarised light due to reflection from non-metallic surfaces. This results in a noticeable increase in sky and foliage saturation, as well as a sharper image when shooting in hazy conditions. A linear polariser differs from a circular polariser in that it does not support the use of a camera's autofocus or auto-exposure functions; it is best suited for use with manual cameras, such as rangefinder cameras, which do not rely on internal mechanisms to determine focus or metering settings.

This filter is constructed from Water White glass and is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and polishing it flat to a tolerance of 1/10,000th of an inch. It has a filter factor of 4, requiring two additional stops of exposure for normal results, and measures 5.65 x 5.65" / 143.5 x 143.5 mm.


- Compared to a standard polariser, the Ultra Pol design strives to increase the polarising effect for greater reflection reduction and greater colour saturation.
- Arranges and filters directionally polarised light perpendicular to reflected light allowing absorption of much of the light.
- Reduces haze in distant landscapes and provides more saturated and vivid colours.
- Strongest effect when used at 90° to the sun.
- Water White optical glass for excellent clarity.
