CIRCULAR POLARIZER FILTER for Canon Powershot G9

CIRCULAR POLARIZER FILTER

The Circular Polarizer Filter produces deeper colored blue skies, which at the same time creates a striking contrast with white clouds. Minimizes light reflections from glass and water, reduces glare from non-metallic surfaces. Provides a general color saturation to both cool and warm tones.

The Circular Polarizer Filter provides the same filter effects as a Linear Polarizer, but is designed to work with auto focus cameras with beam splitting metering. The Circular Polarizer has linear polarizer construction plus a built-in "Wave Retardant" to ensure proper exposure. The linear element polarizes the light, and the wave retardant de-polarizes it, and then the beam-splitting meter polarizes the light again for proper exposure.
