I want to confirm before I buy, will be getting a B+W UV filter and probably ND106/ND110 for olympus m4/3 9-18mm (18-36mm equivalent). Would like to know if both filters are usable at the wide end (9mm), will there be any vignetting. Online search on the filters state usable on wide angle lens, but how wide is wide?

Will be getting from the mass sales forum.
