„The variable ND filter let it go a lot easy to clean“said Kröher after the test. When there was light rain, no water got between the polarizing filters and you could easily set the filter to the desired time using the attached table.

In Brittany, the filter was briefly showered with salt water when there were strong waves. And here too, after cleaning, no effect at all was visible.
