B+W Filter ø82 XS-Pro Digital ND Vario MRC Nano

The XS-Pro mount offers an index setting, allowing the photographer to set the density between +1 and +5 stops. MRC by B+W is not only an extraordinarily effective multiple layer coating, it is also harder than glass, so that it protects filters from scratches (for instance when cleaning the filters), and it is also water and dirt repellent, thus facilitating filter maintenance.
