About B + W 52 Circular Polarizer

Highly efficient standard 52mm circular polarizing filter for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings.

B + W Polarizers increase color saturation and reduce reflections. The neutral gray color and plane parallel polarizer material guarantee optimal image results. High-quality optical glass ensures excellent pictorial quality. The filter factor varies according to how the filter is positioned in relation to the sun. Filter factor is between 2.3 and 2.8.

Linear and circular polarizers both consist of a linear polarizer foil but differ in their construction in the following way. Modern SLR cameras have a beam-splitting prism that sends part of the incoming light to the meter and part to the viewfinder. The effect is that the light entering the meter is partially polarized by the beam-splitter.

A linear polarized placed on the lens of such a system will act as a second polarizer and block light to the meter by a degree dependent on the angle between the prism and the polarizer on the lens. The result is incorrect exposure/aperture values from the meter. The circular polarizer circumvents this problem through the addition of a 1/4-wave retarder, or delay, foil. This ensures that the linearly polarized light is changed into a rotation that appears unpolarized to the meter, resulting in proper exposure/aperture readings.

Great for photographing artwork


from East Lyme, CT  -  Pro Photographer

I bought this filter so I could photgraph my paintings without getting distracting glints of light reflecting off the peaks of highly textured oil paint. It does exactly what I hoped it would do without altering the validity of the colors of my artwork.


B&W Polarizer Filter


from NH  -  Photo Enthusiast

Well made product. Worth the additional funds.


Good quality product


from Michigan  -  Photo Enthusiast

Wanted a Polarizing filter for landscapes that would be less prone to flare under certain lighting conditions. This product fits that need.


Had to send it back.


from Carlisle, PA  -  Photo Enthusiast

I could not use this product. The polarizing ring was so stiff, it was difficult to turn. Using with a lens hood was impossible.




from on the edge  -  Photo Enthusiast

I really wanted to love this filter - brass ring, German-made - I love old-world quality - but I was ultimately disappointed with this product for several reasons. The MAIN problem I had was trying to clean the filter in the field. On a recent trip to the canyons of Utah, the filter became unusable after I tried to clean it. My normal lens/filter cleaning procedure - which has worked successfully for me for 40 years on a variety of lenses and filters from various manufacturers - did NOT work on the B&W filter. The filter surface turned into a smeary mess which I was not able to remove until I could get to warm soapy water - not easily found in the deserts of Utah. My second biggest complaint with the B&W filter is this: It's hard to rotate. Polarizers rotate in their mounting ring so the photographer can adjust the desired degree of polarization for a particular shot. This filter is slim (thin), and B&W has put serrations on the front of the rotating part for a better grip. But because there was so much internal resistance, the serrations cut into my finger tips like a circular hacksaw blade. I'm all for tight tolerances, but this is ridiculous! I've owned several other brands of polarizing filters and they were all much easier to use than this one from B&W. Another issue was with the lens cap that comes with the filter. It doesn't fit tight enough for me to trust it to stay on the filter in my backpack. I didn't want the unprotected face of an expensive filter rubbing against other items in my backpack, so I felt it was necessary to remove the filter before putting the camera in my backpack, even when there was a good chance that the filter would be needed for my next shot. Then there is the plastic box it comes in - which I found to be irritating in the extreme. For one thing, it's much bigger than it needs to be - 88 mm square for a 52 mm filter. The box hinges open, but there are no markings on the top to tell me which edge of the box opens - it's slow to look at all 4 edges to find the one that opens. And once you find the edge that opens, it's very difficult to open it. You have to dig one thumbnail into a certain spot while pulling up on the lid; not so bad once I figured it out, but until then it was frustrating. Some filters which cost 1/3 what I paid for this one come with storage cases which are far more elegant and convenient to use than this one. I have no complaints with the results I got during the brief periods when the filter was clean enough to use, but considering the other issues, I cannot recommend this filter.

Circular polarizer great in Grand Canyon


from Seven Fields, Pa.  -  Photo Enthusiast

Shooting through the glass of a helocopter was no problem as I was able to 'tune out' the reflections from the chopper glass.
