I'd considered the Fuji wide adapter, which does seem to give excellent IQ, but I can't really afford to spend that much. So I am considering the alternatives from ebay.
Anyone considered (or even got) a set like the following? Any comments (and yes, I know they wont be quite up to snuff by comparison with the Fuji branded one)
