Elizabeth U. ★★★★★ Oct 20, 2026

It locks my 37mm lens threads onto a 55mm filter without any wobble, and the precision machining shows in how flush it sits. I’ve used it on a couple of shoots now and it hasn't loosened once. Exactly what I needed for adapting my old filters.

I was worried about threading issues, but this ring screws on smoothly without any wobble. It securely holds my 55mm filters on a 37mm lens, making my kit much more flexible without breaking the bank.

Owen I. ★★★★☆ Oct 21, 2026

I’ve been using this ring to attach a 55mm filter to my 37mm lens, and the threading feels solid—no wobble or cross-threading issues. The anodized finish seems durable, and it sits flush without any light leaks. Just wish it came in a slightly more compact package.
