NiSi 77mm 濾鏡轉接環 用於 Nisi 150mm Q 濾鏡支架 (Canon TS-E 17mm)

Got this to mount my big filter holder on a non-Canon lens, and the threading is precise—no wobble at all. It clicks on securely and lets me use my 150mm setup on more lenses.

Finally, a way to use my 150mm filter setup on a smaller lens without buying a whole new system. The adapter ring screws on smoothly and holds the holder firmly, though it does add a bit of bulk to the front. Working perfectly with my 77mm thread lens so far.

The adapter ring feels solid and locks onto the 77mm thread without any wobble, which is exactly what I needed to pair my 150mm holder with a different lens. Took a bit of fiddling to get it seated perfectly, but once it's on, it stays put.
