Circular Polarizer - 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 colors providing better contrast. The effect 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 polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).

Comments about Hoya 49mm Circular Polarizer Glass Filter:
I bought to use on Sony Nex-5 with 18-55mm Lens.
The quality is OK, you can take great outdoor photos, but using at 18mm the border of lens appears.

Comments about Hoya 49mm Circular Polarizer Glass Filter:
It does what it it is supposed to do. It is fairly thick and to me it is a good attribute. It is much easier to remove from the lens when needed and rotate with lens hood on.
