B+W 77mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter
Key Features
  • Circular Polarizer Filter
  • 99.5% Transmission, Kaesemann Foils
  • 2 to 2.8x Filter Factor, +1 to 1.5 Stops
  • Helps to Eliminate Reflections and Glare
The B+W 77mm 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 77mm 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 rotating 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.

Is it normal to have a polarized "dark" blotch ...

Is it normal to have a polarized "dark" blotch when using the polarized side? I've used many similar filters before and none of them do this.
Asked by: Kris
No, a dark blotch is not normal, this filter should give relatively even results throughout.

Does B+W 77mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter have front threads to screw in B+W 77mm Vario ND filter and/or B+W 77mm 702 GND (0.6) filter?
Asked by: Sourav
I don't use a front filter, but there appears to be a thread/groove in the front and B+H's site under the filter specs, say: "Front Accessory Thread / Bayonet 77 mm." I hope this helps.

question

Will I be able to attach my Cokin P filter set adaptor to the front of this filter?
Asked by: Anonymous
As the B+W 77mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter has 77mm front filter threads, if you wish, yes, you may purchase the Cokin P Series Filter Holder Adapter Ring (77mm), B&H # COARP77, to connect the Cokin P filter holder to the front of the circular polarizer filter.
