Promaster 4991 52-58mm ステップアップリング

I was worried about fit with my odd lens sizes, but this ring threaded on smoothly and held tight without any wobble. The metal feels solid and it added barely any extra weight.

Finally got this step-up ring so I can use my 58mm filters on my 52mm lens, and the threading is smooth as butter—no wobble or cross-threading when I screw it on. It's lightweight but feels solid, and the fit is snug enough that I don't worry about it coming loose mid-shoot.

Does exactly what it says—threads smoothly onto my 52mm lens and holds a 58mm filter snugly with no wobble. Only wish it came with a little more grip texture for when my fingers are cold, but for the price it's a no-brainer.
