Mounts


An important element in a perfect B+W filter is a high-precision filter mount. It must be easy to hold, easy to screw on and off the lens, and fit exactly. The filter glass is perfectly plane and is screwed securely in place. It fits without play and tension. B+W filter mounts are closely toleranced and have very small dimensions. Even with the standard F-Pro mount on wide-angle lenses, photos without vignetting are possible.

Filter Types


When manufacturing our many different B+W filter types, only the finest quality sanded and fine-polished optical filter glass is used. The result is homogeneous, plane-parallel, streak-and bubble-free filter glass for the highest photographic demands.

Coating Systems


A key criterion for an outstanding filter is the coating. Quality begins in front of the lens, and that is, of course, where the filter is placed. A filter must not impair the performance of the optics.

Accessories


Those of us who want to shoot photographs successfully and with pleasure should make sure that they have reliable good-quality equipment. The focus should not only be directed toward cameras and lenses, but should also include the little things that are sometimes overlooked as seemingly unimportant. For this reason, the B+W filter range has been expanded to include accessories that, in combination with filters, are necessary and useful.
