    So far i am very impressed with this new variable filter. Technology is advancing so quick i love it. Ill be doing alot more tests with this but i think this will be replacing my Firecrest ND filters.

    But you know that varibale NDs are polarizers, do you? You may get side effects on reflections and on front panes of cars, for example.

    Very interesting. Never seen that filter before. Wonder how it compares to SLR magic variable ND. Seems it don't have ability to rotate all filter stack to adjust polarization angle X effect. Or maybe because PowerxND Mark 2 use more complicated optical technology it don't need that adjustment anymore? Can we expect further tests? I can suggest test it at the clear sky or flat white wall to check polarization X effect. Also wonder if in have bokeh cross hatching pattern effect.
    I like equal front and rear thread sizes.
