Q: 1. Would this ring permit the use of 55mm threaded filters on a lens with a Series VII filter-thread? The Leica R 90mm f2 (old version, not the later version) is the lens I have in mind.

A: No, that adapter is for lenses that have a 54mm thread. Series 7 is not 54. If you have a retaining ring, most of those are 54 mm it might work. But the adapter alone will not work. This is a retaining ring, General Brand Series 7 Retaining Ring BH #GBRRS7 https://bhpho.to/3bJHVPU
