1. Clears up haze in distant landscapes and provides more saturated, vivid colors.
2. Strongest effect when used at a 90° angle from the sun.
3. Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
4. 2.5x filter factor reduces exposure by 1.3 stops.
5. Multicoated to prevent internal ghosting and reflections.
6. Aluminum-alloy filter ring for durability while remaining lightweight.
7. Filter ring can be rotated to adjust the intensity of the polarization effect.
8. 67mm front filter threads allow for use with other filters.
9. Side knurlings to provide a more textured grip when mounting or removing it from a lens.
