B+W Series 8 Kaesemann Circular Polarizer MRC Filter
Key Features
  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • High Efficiency Kaesemann Foils
The B+W Series 8 Kaesemann Circular Polarizer MRC 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 Kaesemann Overview

The B+W Series 8 Kaesemann Circular Polarizer MRC 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-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. This filter features a brass filter ring for increased durability and is compatible with Series 8 filter holders.

Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° 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.
Kaesemann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils.
Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.

question

Will this filter fit my Canon 24-70mm f2.8 lens?
Asked by: Anonymous
The Canon 24-70 2.8 II uses an 82mm filter. Here is the link for the correct filter: https://<a href= http://www.bhphotovideo.com/c/product/1141526-REG/b_w_1081479_82mm_xs_pro_mc_kaesemn.html target= _blank >www.bhphotovideo.com/c/product/1141526-REG/b_w_1081479_82mm_xs_pro_mc_kaesemn.html</a>

question

What is the size on this?
Asked by: Anonymous
In this instance, Series 8 denotes the use of this filter. It does not have a common measurement such as 52mm for instance. It is part of an older design of filters called Series filters, which were threadless filters that fit inside various lens hoods or other specified adapters. They were more commonly used on lenses pre-dating SLR cameras. Series 8 filters have a diameter of 63.5mm. Do not purchase this particular filter unless you are certain the lens you have requires a Series 8 filter. If you are not sure feel free to send us an email to [email protected] and specify what particular lens you are inquiring regarding, and we can confirm what size filter it may require.
