ProMaster Step Down Ring 46mm-37mm

Was a bit worried about getting the wrong size, but this 46mm-to-37mm ring fits perfectly snug on my lens and doesn't wobble at all. The precision machining is obvious, and it lets me use my smaller filters without any light leaks.

This ring threaded onto my lens with no cross-threading or wobble. Finally got my 37mm filters working on a lens with a 46mm filter thread.

The threading is buttery smooth and it doesn't feel cheap or flimsy at all. I've been using it to attach my old 37mm filters to a new lens, and it's a perfect fit with no light leaks.
