The Schneider Optics 77mm True-Match Vari-ND MKII - ND 0.45-3.45 feature low profiles, smooth rotating rings, and clear marks for choosing strengths while shooting. The effect is achieved by stacking highly neutral grey polarizing filters within a filter cell and rotating them to block the desired amount of light.
