Haida Bluestone Shockproof UV Filter 77mm

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.

2.5x filter factor reduces exposure by 1.3 stops.

Multi-coated to prevent internal ghosting and reflections.

Thin, aluminum-alloy filter ring helps to prevent vignetting while remaining durable and lightweight.

Filter ring can be rotated to adjust the intensity of the polarization effect.

82mm front filter threads allow for use with other filters.

Top knurling to provide a more textured grip when mounting or removing it from a lens.

Constructed from optical glass for clarity and color fidelity.

Plastic filter case for storage and transport.
