The Haida 67mm Slim Pro II 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.

This filter is constructed from optical glass for clarity as well as color fidelity and features an aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect. To prevent internal ghosting and reflections, the glass includes 10 layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters.

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.

67mm 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.

Q: 10. When using this polarizing filter on my D7100 with 18-105 or my 70-200 lenses and with a UV filter you rotate it and then can see the affect in the viewfinder from light to near dark. What should it be rotated to ? ie what result is achieved?Also, with the lens hood on it is difficult to rotate the filter but I assume I am to rotate it for the desired affect to be achieved? Or does this camera automatically adjust for the filter?

A: You rotate a circular polarizer to achieve a bluer sky or to cut glare from reflective surfaces. The camera will not automatically adjust for the filter, since this is a totally mechanical action. You should rotate the filter until the effect you are looking for has been achieved.
