With the T-PRO filter line, it has been possible to adapt the design to the increasingly compact camera equipment and to create a slim profile. The titanium-colored finish gives the filter line a special touch and is optimally suited for all focal lengths, including wide-angle and telephoto lenses. The special functional coating facilitates the screwing in and out of the filter with its sliding properties. As is customary with B+W, the base material of the filter mount is made of sturdy brass. The manufacturing process is carried out at the highest level with minimal tolerances.
