Product details

The 77mm Teru Teru Bouzu High-Density (HD) Circular Polarising Filter (CPL) represents the next generation of dynamic Asahi Optical Glass filters.

This filter, with its hardened glass, has the tensile strength of traditional filters of similar fabrication. This filter is also of great use in today's digital market where sensors are more sensitive to reflected light. Asahi Optical Glass incorporates special coatings that reduce these internal reflections and, thereby, promote a clearer, brighter and sharper image.

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.
