No problem if the whole mechanism has 2 rings able to be moved.

First ring determines the filter factor, then rotate the second ring (and therefore both filters) until the polarized light comes through.

You can test it for yourself if you have two filters and a LCD/TFT monitor, it's light is polarized.



Don't know if this mechanism is used by Kenko.



Ciao, Walter
