Promaster Stepping Ring - 40.5mm-49mm

The threading’s been perfectly cut—my 49mm polarizer screws on without any wobble. It solves the problem of mismatched filter sizes without adding noticeable weight to the lens.

The machining on this ring is so smooth that it threads onto my lens without any wobble. I’ve been using it to mount my 49mm ND filter, and it stays perfectly secure even during long exposures.

Finally got this stepping ring to use my existing 49mm filters on a smaller lens, and the anodized finish feels sturdy enough for daily use. The threading catches smoothly without any binding, which makes swapping filters quick.
