HOYA B-30 B30 Green G ( X1 ) Filter for camera lens SLR DSLR This a listing from a recovered warehouse storage for a photography shop that was closed a decade ago, I'm not an expert but with some online help knowledge we made this listing happen. It is a vintage Pre-Owned conditon, that might have minor blemish or storage/climate related wear, we tried to clean if needed as we could, please don't mind our short description so please see pictures as it is part of the description and explain item conditon worth a thousand words 😀.
