ProMaster ステップアップリング – 40.5mm-58mm

Had trouble finding a 40.5mm to 58mm step-up locally, so this was exactly what I needed. The threads are smooth and align perfectly with both my lens and filters.

Bought this to use an old 58mm filter on a small lens, and the threading is smooth and precise — no wobble or cross-threading issues.

Threaded on smoothly without any cross-threading, which was my main worry. I just wish it came with a little more grip for tightening by hand. Works perfectly with my 40.5mm lens for using larger filters.
