Promaster Stepping Ring - 46mm-52mm

The threads are cut perfectly clean, so the ring screws on without any wobble or binding. It let me mount my 52mm polarizer on my old 46mm lens for some landscape shots this weekend.

I was pleasantly surprised by how smoothly this ring screws onto my lens threads no grit or wobble. It lets me use my 52mm filters on a smaller lens, which saves me from buying a whole new filter set.

Finally, I can use my 52mm filters on my old 46mm lens without any wobble or light leaks—the threading is precise and smooth. It's a simple solution that saves me from buying a whole new set of glass.
