The Carl Zeiss T* Circular Polarsing Filter from Zeiss helps to reduce
reflections and glare by filtering out light that has become polarized
due to reflection from a non-metallic surface. A polarizer is able to
absorb much of this polarized light and, in turn, increase the
saturation of skies and foliage, cut through distant haze, and minimize
reflections in glass and on water. A circular polarizer differs from a
linear polarizer in that it integrates a quarter wave plane within a
linear polarizing filter. The addition of this helps to circularly
polarize reflected light, which enables your camera's autofocus and
auto-exposure mechanisms to function properly. The T* anti-reflective
coating helps to reduce reflections on the filter's surface and promote
a better light transmission for high quality imagery. The filter ring is
designed with a slim profile to allow its use on wide angle lenses, but
front filter threads are still available for the use of additional

Circular polarizers are ideal for use with digital cameras and autofocus
lenses where a linear polarizer will often disrupt auto exposure and
