NiSi 黃銅專業 49-58mm 升級環

The brass construction feels solid and precise, threading onto my lens without any wobble or tight spots. I’ve had zero issues with it holding filters securely during a long shoot.

I was worried this step-up ring might add bulk, but it's impressively thin. The brass construction feels solid and hasn't shown any signs of binding or sticking on my lens. It's a simple, reliable solution for using my larger filters.

The brass threading is noticeably smoother than my old aluminum rings — it screws on without any grinding. Fits perfectly flush on my vintage 50mm lens, no wobble at all. Exactly what I needed for my CPL filter setup.
