The Singh-Ray Z-Pro Series LB (Lighter, Brighter) Neutral Circular Polarizer Filter is compatible with a Cokin Z-Pro Series Filter Holder. It 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 and the frame it is mounted in features a serrated edge so that the filter can be easily rotated in order to adjust its effect while placed within a compatible holder.

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
1.5x filter factor reduces exposure by two-thirds of a stop
Constructed from optical glass for clarity
Filter frame features a serrated edge so that the filter can be easily rotated and its polarization effect adjusted while placed within a compatible holder
