Q: 4. Am planning to do these 1. step up from 37-52mm and then 2. step up from 52-67mm 3. Mount a 67mm CPL filter Will I be introducing vignetting in this setup? Appreciate all comments. Thanks in advance.

A: Depends on the lens you're using. But its likely you wouldn't get any vignetting from the filter due to the filter being so much bigger than the lens diameter. A random suggestion I think would help to simplify the process, consider looking into this step up ring. It's from 37-67mm all in one. So you wouldn't need to stack step-ups. https://www.bhphotovideo.com/c/product/1355342-REG/benro_dr6737_67_37mm_step_down_ring.html?sts=pi&pim=Y

Q: 5. 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
