Promaster Stepping Ring - 52mm - 49mm

The threading is buttery smooth and it screws onto my lens without any wobble. I've tried cheap rings before that bind up, but this one fits perfectly and holds my polarizer tight.

Finally a stepping ring that actually threads on smoothly without any wobble; the precision machining on this 52-to-49mm adapter is noticeably better than the cheap ones I’ve tried before. It let me use my favorite 49mm CPL on a new lens without any light leaks, and the fit feels totally solid.

Bought this to adapt an old 49mm lens hood onto my new 52mm lens, and the aluminum threading fits perfectly without any wobble. The ring is thin enough that it doesn't block the front element at all.
