Yes, very good video filter.

If the filter is screwed on, it is compatible (good diameter), do not try to screw it in all the way, ie half a turn less, this can be a solution not to replace it.

Hello, possible it is a variable nd. The principle of composition / construction of nd variable determines that it is possible to have a cross at the max. If you do not want to have a large cross effect at the maximum, I recommend our crossless series filters ND2-32 or ND8-128. Sincerely.
