Hoya 82mm alpha Circular Polarizer Filter

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.

Clears up haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° angle from the sun.

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

Non-coated.

Approximately 96% average light transmission.

3 to 4x filter factor reduces exposure by 1.6 to 2 stops.

Constructed from optical glass and precision milled aluminum frames.

Plastic filter case for storage and transport.
