Promaster Stepping Ring - 49mm-58mm

The threading is smooth and precise, so my 58mm filters screw on without any wobble or cross-threading. I’ve been using it to adapt my 49mm prime lens and it feels solidly machined, not cheap like others I’ve tried.

Finally, an adapter ring that actually threads on smoothly without any cross-threading—this 49mm-to-58mm ring fits tight and secure. I use it to mount a bigger polarizer on my vintage lens, and it hasn’t loosened up at all during shooting.

Bought this to put a 58mm ND filter on my 49mm lens, threads were perfectly smooth and it screwed on tight with no wobble. Works exactly as it should.
