NiSi 황동 어댑터 링 세트 (NiSi 100mm V5/V5 Pro/V6/V7/C4용)

The brass threading is buttery smooth when twisting these on, and having the whole set in one bundle saved me from hunting down each size separately. I’ve swapped between lenses on the V7 holder without any wobble or cross-threading, which is exactly what I wanted.

The brass threads are noticeably smoother than my old adapter rings, and the bundle covers every filter size I own. Snaps into the holder with zero wobble.

Wasn't sure I needed the whole bundle, but having every step-up size on hand for my 100mm holder has saved me mid-shoot more than once. The brass feels solid and doesn't bind like the cheap aluminum rings I've used. Threads stay tight even with a heavy filter stack on top.
