The Hoya HRT Circular Polarizing Filter is
unique in its design since it incorporates a High
Rate Transmission
film that permits more visible light to be passed through the filter while still
producing the same degree of polarized light.
This filter now permits the equivalent of 1/3 stop more light to be taken in yet
it still filters the same amount of polarized light. This can be a huge benefit
to users of both digital and HD technology cameras and lenses.
Light rays which are reflected become polarized. Polarizing filters are used to
select which light rays enter your camera lens. They can remove unwanted
reflections from non-metallic surfaces such as water or glass and also saturate
colours providing better contrast. The effect can be seen through the viewfinder
and changed by rotating the filter.
This New filter also contains UV properties which aid in eliminating the bluish
cast on cloudy days or in open shade.
The effect of the polarization can be seen through the viewfinder and changed by
rotating the filter. The filter factor varies according to how the filter is
rotated and its orientation to the sun.
Note! Circular polarises are specifically designed for use with auto-focus SLR
cameras (They will also work on manual systems with no problems)

Everything was fine. The shipping costs a bit expensive, many other on-line stores have free "global worldwide shipping".
