The NiSi 77mm Pro 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. 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 non-metallic surfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
The NiSi 77mm Pro Circular Polarizer Filter is constructed from optical glass for clarity as well as color fidelity. It features a brass filter ring that can be rotated in order to adjust the intensity of the polarization effect while enhancing durability and jamming prevention. Additionally, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces to create an improved beading effect when in contact with water for greater cleaning efficiency.
- 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.
- NiSi Optical Nano Coating creates an improved beading effect when in contact with moisture for greater cleaning efficiency.
- 2 to 2.5x filter factor reduces exposure by 1 to 1.3 stops.
- Constructed from optical glass for clarity.
- Brass filter ring helps to prevent jamming, and provides additional strength.
- Filter ring can be rotated to adjust the intensity of the polarization effect.
- Side knurling to provide a more textured grip when mounting or removing filter from a lens.
- 77mm front filter threads allow for use with other filters.
- Plastic filter case for storage and transport.
