With the T-PRO filter line, we have succeeded in adapting the design to the increasingly compact camera equipment and making the profile narrow. The titanium-colored finish gives the filter line a special touch and is ideally suited for all focal lengths, including wide-angle and telephoto lenses. The special functional varnish with its sliding properties makes it easier to screw the filter in and out. As is usual with B+W, the basic material of the filter mount is sturdy brass. The manufacturing is carried out at the highest level with minimal tolerances.
