Q: 6. 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: 7. Will the Sensei step up rings work for freewell magnetic filters?

Q: 10. Can this be used in a 114 Matte Box? Hypothetically want to take a Sigma Art Lens and used a Bright Tangerine Mistfit Atom.

A: The Sensei 72-95mm Aluminum Step-Up Ring allows you to connect a lens with a 72mm front thread to a 95mm thread adapter ring. Unfortunately, you cannot replace the adapter ring for the matte boxes with a step-up ring because they are designed as a proprietary system.
