NiSi Brass Pro 72-77mm 升級轉接環

Installed this step-up ring on my 72mm lens and the 77mm filter screws on smooth as butter—no cross-threading worries. The brass construction feels solid and hasn't shown any signs of binding like my old aluminum rings did.

The threads are buttery smooth—no annoying binding or cross-threading when screwing it onto my lens. It’s barely visible, which is exactly what I wanted for stacking filters without added bulk.

Finally, a step-up ring that doesn't get stuck on the lens—the brass construction threads on smoothly without binding. I've been using it with my 77mm CPL and it feels reassuringly solid.
