The 77mm QuartzLine Circular Polarizer Filter from PolarPro helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.
FEATURES
- 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.
- The 2.5x filter factor reduces exposure by 1.3 stops.
- Constructed from quartz glass for enhanced durability.
- Multicoated to prevent internal ghosting and reflections while promoting clarity as well as color fidelity.
- Brass filter ring helps to prevent jamming and provides additional strength.
- Filter ring can be rotated to adjust the intensity of the polarization effect.
- 77mm front filter threads allow for use with other filters.
- Side knurlings provide a textured grip when mounting or removing from a lens.
- Plastic filter case for storage and transport.
- Microfiber cloth for cleaning and maintenance.
