Promaster Step Up Ring - 55mm-72mm

This ring threaded onto my lens without any wobble, which was a relief after struggling with a cheaper plastic one before. The machining feels solid and precise, and it instantly made my 72mm filters usable on a 55mm lens.

Finally got around to testing it with my 55mm lens and 72mm filters, and the threads are so smooth that mounting takes zero effort. Never had a ring this precisely machined before, and it locks on tight without any wobble.

This step-up ring feels solidly machined, it threaded onto my lens and filter without any wobble or cross-threading. Exactly what I needed to use my larger filters on a smaller lens, and it locks in place securely.
