I have a series VI adapter ring that mounts exactly on my newly acquired Kodak Monitor with 101mm f4.5 Anastigmat Special lens. I would like to attach a lens hood to it. I happen to have a beautiful round black metal hood with 46 mm thread. It won't thread on the series VI thread (46 mm is slightly larger). Is there such as thing as series VI to 46 mm step up ring? I have plenty of 46 mm filters so I really would not want to have to buy series VI filters and build up a system just for this Kodak folder.
