Just for your info: there are also fader ND filters. I know the LCW ND filter MarkII 77mm goes from ND-2 until ND-400 (2-8 stops). I have no clue how quality is of these ones vs normal constant ND filters.


I don't have any experience so someone else must step in here. But it seems quite logical to me how they work.


Good luck,
