프로마스터 스텝업 링 - 40.5mm-43mm

The threading is buttery smooth on both sides, so attaching it to my lens and filter felt secure without any cross-threading worry. Fit my 40.5mm lens perfectly to take my 43mm filters, saving me from buying new ones.

Two of my lenses use 40.5mm threads and this ring lets me share my 43mm filters between them. The threads are precision machined and screw on smoothly without any wobble or cross-threading. Exactly what I needed for a simple fix.

The 40.5mm to 43mm conversion feels precise, no wobble or cross-threading when I attached it to my lens. It's lighter than I expected, which is nice for keeping the kit balanced. Happy with the solid metal build, no plastic feel whatsoever.
