Promaster Stepping Ring - 52mm-72mm

The threading is buttery smooth and locks onto my lens perfectly, no wobble at all. I was able to mount my larger 72mm filters without any vignetting on my wide-angle setup. Exactly what I needed for this conversion.

The threads on this ring are cut so cleanly that my lens cap screws on without any of that grinding feeling I've had with cheaper adapters. It's slim too, so I don't notice it adding bulk between the lens and my new 72mm filter.

Finally a stepping ring that doesn’t wobble or cross-thread when I mount my 72mm filter onto the 52mm lens. The machining is spot-on, threads engage smoothly every time. Took the guesswork out of my kit.
