Promaster Step Up Ring - 43mm-58mm

The threading is clean and precise, so it screws on smoothly without any wobble or grinding. I’ve used it to pair a 58mm filter with my 43mm lens and it holds perfectly tight every time.

Finally a step up ring that doesn't cross-thread on the first try — the machining is noticeably smooth. Used it to mount a 58mm filter on my 43mm lens and it held perfectly with no wobble.

Threads aligned perfectly on my 43mm lens and the 58mm filter screws on without any wobble. Precision machining really shows here — the ring feels solid and not flimsy like some cheap adapters I’ve had.
