The B+W 37mm Standard F-Pro Circular Polarizer Multi Coated Glass Filter is a circular polarizing filter that reduces reflections from non-metallic surfaces such as water, glass, and glossy paint. Objects and people behind surfaces such as shop windows and car windshields become visible without image processing. B+W polarizing filters augment the purity of the intrinsic colors and increase color saturation. This filter is often regarded as the most important filter for photography.
F-Pro mount is thinner than the Standard mount, so now it can be used on many wide-angle lenses without the danger of vignetting. An exact focal length limitation cannot be stated, because vignetting depends not only on the height of the filter mount, but also on the design of the front of the lens. Nevertheless, the following can serve as a guide: The B+W standard filter mount F-Pro can be used without vignetting on 35 mm camera lenses with focal lengths of 35 mm, most 28 mm lenses, and in many cases even on 24 mm lenses. Another advantage of the F-Pro filter mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. This prevents the retaining ring from being accidentally loosened during the removal of an additional filter or a lens hood that has been screwed in too tightly.
