Promaster Step Up Ring - 37mm-55mm

The threads are buttery smooth and the aluminum feels solid—mounted perfectly on my lens without any wobble. I needed this to use my 55mm filters on a 37mm lens and it works flawlessly.

Was a bit worried the threading might be off, but this ring fits my lens snugly and doesn't cross-thread at all. Feels solidly machined, and now I can use my larger 55mm filters on that old 37mm lens.

Threads on perfectly with zero wobble, so my 37mm lens cap now fits my 55mm filters without any adapter fuss. It’s solidly built and hasn’t loosened once in a month of daily use.
