The rectangular B+W 701 and 702 graduated ND filters are suitable to be used with filter holders such as Lee and Cokin Z, as well as for all other compendia with filter channels designed with 100 mm width and 2 mm thickness slots. The graduation of the B+W sheet filter can be exactly aligned in the compendium by moving and rotating the horizon accordingly. The filter sheets are dimensionally stable thanks to the glass substrate and therefore cannot warp or distort.
