NiSi Brass Pro 58-77mm 轉接環

Finally, a step-up ring that doesn't get stuck—the brass threads have held up perfectly after several lens swaps. It's slim enough to not add noticeable vignetting with my wide-angle filter setup.

The brass threads are noticeably smoother than the aluminum rings I’ve used before, and the step-up fit on my 58mm lens is snug with zero wobble. It’s a pricey little piece, but the machining feels precise enough that I trust it with my 77mm filters.

Screwed it onto my 58mm lens and the threading was perfectly smooth with zero wobble, which was my main concern. It's thin enough that I can still use my lens cap without any issues.
