The B+W 67mm 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 66-044842 Overview

The B+W 67mm 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.

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. They feature a brass filter ring for durability as well as jamming prevention.

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.
Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.

I am new to filters, is there adjustment i can do with this circular polarizer? like turn it after i have screwed it onto the lens? or is the glass just a direct screw fit and doesnt adjust?
Asked by: Mohammed
Yes, all circular polarizers rotate to adjust the polarization effect.

question

Can I use this filter in conjunction with a Cokin Z-Pro holder so that I can use ND filter?
Asked by: Tom S.
Unfortunately, there is not a way to connect the B+W 67mm Circular Polarizer MRC Filter onto the front of the Cokin Z-Pro holder. If you wish to use this, you would have to use the filter on your lens, then connect the adapter ring for the holder into the filter threads on the front of the Circular Polarizer filter, then connect the Z-Pro holder to the adapter ring. Do note that this setup will make it hard to rotate the circular polarizer, but would be the option that would let you use the above with the Cokin Z-PRO holder.

question

Does it really worth to spend $40 more and get the B+W Kaesemann filter?
Asked by: Pouya O.
This is a quality screw-on filter - the metal work is first quality. Less expensive filters use metals like aluminum of which the screw mount is easily stripped. This can cause a filter to be jammed on the lens and potentially damage the lens mount. At the least it means time lost trying to remove the jammed filter.

question

Is there an important difference in quality between this and the B&W Kaesemann 67mm Circular Polarizer filter? I'm only a photo enthusiast, but the quality of my images is, as for anyone else, very important to me. So I'd really like to know the best CP to purchase. Most of my images are taken outdoors and I live in SoFL...always bright and sunny. Thanks in advance
Asked by: Anonymous
The difference between a B+W standard circular polarizer and a Kaesmann circular polarizer is that Kaesmann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils. These are some of the highest quality CP filters you can use: http://bhpho.to/1nuNyRv
