1 pointAdam: I see. Yes, I had to remove the rubber ring but have not had any problem with the tape failing (yet). The rubber ring stays off since the lens is only used underwater. Based on your comments, I put a strip of gaffer tape over the existing tape. It fit quite well and should keep things together. Thank you for explaining.
