About B + W 77 Circular Polarizer

Highly efficient standard Circular Polarizer SC Single Coated Glass 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.

good quality product


from laurel, md  -  Photo Enthusiast

Good quality filter but price you have to pay over performance is too high, honestly I couldn't find much difference with my $7 cheap filter from other brand.


decent filter but too expensive for it'sperformance


from laurel, MD  -  Photo Enthusiast

Build quality is great does what it does but for about $145 I thought it will be way better than my old $6 cpl but honestly I couldn't see any difference even under careful pixel peeping (reducing reflection, making cloud pop). There could be something better that I don't know but for performance it was exactly same as my $6 cpl, I'm so disappointed on b+w. I'm sending this back.


I would buy this product again

77 mm Polarizer


from Dallas, Texas  -  Photo Enthusiast

great quality glass, can be thinner


Excellent Value


from Udon Thani, Thailand  -  Photo Enthusiast

Value is completely different from cost. There are cheaper CP filters but for me, the extra value of brass construction justifies the additional cost of this filter


Best one to carry

Shopper  Why Did You Choose This?
WAYNE H  I needed a polarizer to help reduce reflections off of metal and glass surfaces in my photos. It also helps to darken the tones in the sky in landscape and water photos.
