B+W 52mm Circular Polarizer MRC Filter

BH #BWCPMC52 • MFR #66-044838
B+W
B+W 52mm Circular Polarizer MRC Filter
Key Features
  • Helps to Eliminate Reflections and Glare
  • Reduces Haze and Blue Cast in Landscapes
  • Greater Color and Tonal Saturation
  • MRC Multi-Resistant Coating
The B+W 52mm 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 66-044838 Overview

The B+W 52mm 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.

Extremely helpful to knock back and control levels of sheen on objects in nature when shooting macro. Smooth rotation of filter element with minimum of image quality loss.

Have a cannon eon rebel t7 will there be problem fitting on this camera ?thank you Will
Asked by: WILL
It depends on your lens size. I have a t3 and I use the 52mm on my 35-80mm lens. The lens should have a marking indicating the size you need.

question

I have this filter but F-PRO appears on the outside rim. What does this mean? I have also seen C-PRO on some.
Asked by: Anonymous
The F-Pro labeling on B+W filters refers to the mount construction of the filter. F-Pro mounted filters are constructed from brass and feature a front thread.

Do B&H stock any 52mm CPL filters with front filter threads--that are multi coated on all surfaces, including the internal surfaces? Thanks!
Asked by: Paul
I am unable to provide any further info than what Zachariah provided. I find the CPL doing what it has supposed to be doing. I reside in the desert and I need all the help I can get

question

Can I fit Fujifilm XF 18mm f2 lens hood on this filter? Can I also fit fujifilm lens cap on this filter?
Asked by: Vi Cher C.
If you want to use a hood on your polarizer, you need to use a collapsable rubber hood that will thread into the front of the filter. That way, you can rotate the filter without having to remove the hood.

question

i have Olympus 9-18mm lens and Tamron 14-150mm lens, it seems at 9mm or 14mm, there is dark blue areas at the edge of the pictures, is this filter too good for those lens, or is there something wrong of how to handle it?
Asked by: mei s.
You may need a polarizer that is made for wide angle lenses. They are thinner than regular filters so the lens does not see the sides of the polarizer. That is probably what is causing the dark edges when you shoot with the lens at its widest focal length.
