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 narrow. The titanium-coloured 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 lacquer with its gliding properties makes it easier to screw the filter in and out. As usual at B+W, the basic material of the filter mount is made of sturdy brass. Production is at the highest level with minimal tolerances.
