Promaster 5131 72-77mm 轉接環

Made my 77mm variable ND fit perfectly on my 72mm lens — no wobble or light leaks at all. The aluminum construction feels solid enough for daily use.

Needed this to mount an older 72mm filter on my 77mm lens, and the threading is smooth as butter going on and off. The metal feels solid and it doesn't bind or cross-thread at all, so it's doing exactly what it's supposed to do.

This step-up ring fits perfectly and feels much more solid than the cheap plastic ones I’ve used before—the metal threading is noticeably precise. It let me mount my 77mm polarizer on a 72mm lens without any light leaks or wobble.
