Promaster Stepping Ring - 58mm-52mm

The threading is buttery smooth and it screwed onto my lens without any wobble. I've been using it to mount my circular polarizer and it holds tight with no signs of vignetting even at wider apertures.

Needed a way to mount my 52mm ND filters on a 58mm lens, and this ring fits tightly with no wobble. The aluminum feels solid and the threading is smooth, makes swapping filters in the field quick.

Finally, a stepping ring that doesn't cross-thread on me—the precision machining is noticeable as soon as you screw it on. It fits snugly between my 58mm lens and 52mm filters without any wobble.
