Review on 🔌 Enhance Compatibility with Freewell Magnetic Filters and Threaded Filters: Freewell Step Up Filter Adapter Ring 67mm-82mm by Djmikis Parker

Freewell doesn't include a magnetic ring in its filters but I like it better because I buy big round filters and I usually buy boost rings. I like the colors of the Kase magnetic filters compared to the Freewell ND 10 apertures, however I had to buy an extra boost ring to attach the supplied magnetic ring, not to mention the price difference between Kase and Freewell. What I really like about the Freewell Boost Ring compared to the Kase is that the Freewell has a front thread for screwing in your own filters. Kase step-up rings do not have front threads, so you only need to use Kase magnetic filters. Unfortunately, the magnetic filters of the two brands are not compatible with each other with step-up rings, they have opposite polarization. I have Kase ND filters and Freewell Grad ND.
