With the T-PRO filter line, it has been possible to adapt the design to the increasingly compact camera equipment and to make the profile slim. The titanium-coloured finish gives the filter line a special touch and is optimally suitable for all focal lengths incl. wide-angle and telephoto lenses. The special functional varnish with its sliding properties makes it easier to screw the filter in and out. The basic material of the filter mount is, as usual with B+W, sturdy brass. The manufacturing is carried out at the highest level with minimal tolerances.
