B+W 58mm 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 58mm 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 58mm 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.

I've read that this filter can be difficult to turn and remove. Have you had problems with this?
Asked by: Rebecca
The rotation is quite smooth and effortless, to remove you just need to ensure you are gripping the proper part of the filter when you turn it.

question

I've heard that some polarizing and UV filters used with the Pentax 31mm f/1.8 Limited lens may actually come into contact with the lens surface when they are screwed down. Is this the case with the B+W XS Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter.? Would that filter touch the glass when screwed on the 31 mm Pentax lens.? Thank you,Mike
Asked by: Mike
The filter comes close but does not touch the 31mm f1.8 lens. Screwed down too hard, the outer/polarizer ring may become slightly hard to turn. The same will happen with the filter loose if the thread ring is squeezed between two fingers. The rub between the slim rings is slightly increased. This is not due to the filter touching the lens.
