Can I use any step up ring?
Can I use any step up ring? I have a few 82mm freewell filters from their m2 series. I also bought a step-up ring from freewell to use on a lens with a 77mm thread. The freewell step up ring magnet is very weak and doesn't secure the filter well. I'm wondering if I have to use the freewell step up ring or can I use any magnetic step up ring? Thanks
