The B+W 82mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano 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.

B+W XS-Pro Overview

The B+W 82mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano 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.

Kaesemann High Transmission Circular (HTC) polarizing filters are fitted with polarizing foils which provide 99.5% light transmission that are cemented between plano-parallel optical glass. The resulting sandwich is then precision-polished to achieve accurate plano-parallel surfaces. Finally, they are edge-sealed to protect the foil against humidity.

To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. This Multi-Resistant Coating (MRC) also offers further protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. The Nano coating associated with XS-Pro filters provides an additional eighth layer over the MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

B+W filters are constructed from Schott glass for increased optical clarity and color fidelity. This filter features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention. To further reduce the possibility of vignetting when this filter is in use, the filter ring's outside diameter is slightly larger than the actual thread size. This may prevent the use of some lens manufacturer bayonet hoods.

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.
Multi-coated to prevent internal ghosting and reflections while providing over 99.5% light transmission.
2 to 2.8x filter factor reduces exposure by 1 to 1.5 stops.
Constructed from Schott glass for optical clarity.
Nano coating provides an improved beading effect with water for more efficient cleaning.
Plastic filter case for storage and transport.

The product description says this polarizer's optical density would equal a 1 to 1.5 f-stop reduction. Why would it vary?
Asked by: john
Because polarizers also cut light apparent from filtering stray light which is its primarily function. Usually it's 1 stop and a 1/3 (1.3 stops). It's normal this behavior. It's great for bright settings like beaches to use.

Hi, is there a way to tell what level off polarization you are at when spinning the filter? Or is it just done by eye pretty much?
Asked by: nicholas
I just spin it around and use my eye.

Hi, I have a canon 70D can I buy this polarizer ? Is the same size ?
Asked by: Anonymous
The Canon EOS 70D is a camera. It does not take filters-- lens take filters, not camera bodies. Your specific lens would determine which size filter you would need to purchase.

question

Are these stackable with other filters or the Lee holder system? Im using cannon Len 16-35 version 2. I want to use it combination with my Lee filters such as little big stop, ND grads in soft or hard.Thank you
Asked by: Megan V.
These filters are for a flash, not for a lens.

question

B&H graciously allowed me to return a defective copy of this B+W polarizer that I tested under strong backlighting to have dozens of point-like scattering center embedded in the interior (The test on a Nikon polarizer under than same lighting does not.) What left unanswered is where this situation is common on B+W polarizer? The answer would guide my decision to whether to order another copy of this B+W polarizer or the Nikon/Hoya version.
