I am having a problem finding any ND filters that work with the Anafi. I bought the Freewell Essential collection but unfortunatelly they don't work with the Anafi. The camera faces down when I have the filter on. It cannot stabilize the gimbal, don't know if it is because they are too heavy or any other reason. I try to push them all the way in as some suggested but with no success. Any other reliable brand that is known to work with Anafi. Right now this is a big issue with this drone and I plan to return it if they are no filters available. Thanks for your imput.
