The Vaxis VFX VND-CPL Variable 0.9-2.1 82 mm filter combines the functionality of neutral gray and polarizing: it reduces the amount of light in the frame, saturates colors, reduces glare and reflections from various surfaces. Both measures vary depending on the task. When setting up, it is recommended to first select an ND density value of 0.9-2.1, lock the ring using the screw adjustment knob and adjust the degree of polarization. The filter can be used with lenses with a focal length of 16 mm or more.
