Leica provides a wide array of ultraviolet and circular polarizing filers using the finest materials available for their series of reflex and rangefinder lenses.

Film, as well as video, often exhibits a greater sensitivity to what is to us invisible, ultraviolet light. This is most often outdoors, especially at high altitudes, where the UV-absorbing atmosphere is thinner; and over long distances, such as marine scenes. It can show up as a bluish color cast with color film, or it can cause a low-contrast haze that diminishes details, especially when viewing far-away objects, in either color or black-and-white. Ultraviolet filters absorb UV light generally without affecting light in the visible region.

Polarizer filters give you several key creative features. They evenly increase color saturation of all colors (except black and white), creating deep, rich scenics. They add contrast for dramatic skies and arial shots. They eliminate the whitish glare from highly reflected surfaces like glass and water. Polarizers are two part lenses that rotate, allowing you to select the degree of additional saturation, contrast and glare reduction desired.
