Anyone used this ND vari filter? Genus brand
Oops, forgot to paste.
The 77mm ND Fader Filter from Genus is unique in the world of neutral density filters. Other companies make you buy individual ND filters to meet your needs (i.e. 1-stop, 2-stop, etc.). Genus provides one filter that generates 2-8 stops of neutral density depending on how it is rotated.
