yup, i used the filter. the arrow i am referring to is the one under the wordings on the hood.
the "it" is screwing the rim. i have the exact same set as you, bought from pandabase.
no vignetting if you manage to screw the hood until the arrow is at the top.
Oh that's e problem, I didn't get mine form pandabase...wat model is the filter from Pandabase? How thick/thin is it?
Anyway, even with the rim on, vignetting still occur...mind posting a photo of your lens hood and filter?
