Promaster Step Up Ring - 55mm-72mm

I was relieved to find this ring fit perfectly without any wobble; the precision machining is exactly what I needed to adapt my filters. My old stepping ring always got stuck, but this one threaded on smoothly and held tight.

The threading is so smooth that my 72mm filters screw on without any wobble or cross-threading, and the precision machining is obvious the second you handle it. I've used cheaper adapters before that felt flimsy, but this one locks on solid and has held up through a full day of shooting.

Finally got around to mounting my 72mm CPL on a 55mm lens and it threads on smoothly with zero wobble. The aluminum feels solid enough to leave on the lens between shots.
