B+W XS-Pro overview

  • 1Description

The B+W 72mm 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.

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.
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.

    B+W XS-Pro reviews

    72mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter is rated 4.7 out of 5 by 28.
    Rated 5 out of 5 by from Worth Every Penny We spend well into four figures on our lenses so why on earth would you want to any pinch and not put the best quality glass in front of it. Kaesemann is a great foil and you will notice the difference. The high transmission is not marketing hype but you actually gain as much as a stop. My lenses have gotten rained on and sprayed with mist and the Nano coating really does make keeping the clean easier. I've been doing this for more years than I care to remember and B&W is the only filter I'll put on my glass (and no I don't work for them).

    Rated 5 out of 5 by from Great filter I really like this filter. Produces clean images, minimal vignetting. Its a different color than the non Keasemann I bought a few years back for some reason

    Rated 5 out of 5 by from Very high quality filter I am using this filter on my A7RM2 with 16-35mm Zeiss lens. I was concerned about vignetting but have not seen any. It polarizes very well - even blacking out my LCD screens almost completely. I like how smoothly it turns and there is no wobble between the discs. There is a slight color cast but it's easily corrected in Lightroom with auto color or eye dropper. Pictures are so saturated I have to turn the color down - not a bad thing.

    Rated 4 out of 5 by from Works as expected This polarizer was great, easy to use even tried stacking with ND using front filter threads, well built. I think its common with all wide-lens that polarizer introduces some vignetting. I could notice the same with this filter, so no regrets there.

    Rated 4 out of 5 by from Superior Optics I use this with my Fuji 50-140mm f/2.8 lens, so I didn't want to sacrifice any quality with a cheaper filter. Compared to my older filters, this allows more light to get through yet is effective in reducing glare and unwanted reflections. Also, color seems to be nicely balanced. It is, however, very thin, and I've had some difficulty removing it when attached to a ND filter when shooting waterfalls. I needed to use my filter wrenches to detach it from my ND filter. Otherwise, optically very good.

    Rated 4 out of 5 by from Went with the best Definitely polarizes well and does not block much (good) light. As yet, haven't really used it much so will try to check in later.

    Rated 5 out of 5 by from Polarizer works great with landscapes Photographing landscapes with this filter is a pleasure with the 99.5% light transmission. Very pleased with the results of using this polarizer to enhance landscapes just a bit more to make the image pop naturally.

    Rated 5 out of 5 by from Great! All I can say is it's a B+W filter. I wouldn't put anything else in front of my $1,500-$4,000 lenses.
