NiSi Brass Pro 67-77mm 升級轉接環

The brass construction feels noticeably more solid than my old aluminum rings—threads onto my lens smoothly without any binding or wobble. It's a precision fit that makes swapping filters quick and confident.

I was worried a step-up ring might add wobble, but this brass one locks on perfectly, and the threading feels buttery smooth. My 77mm polarizer now fits my 67mm lens without any light leaks.

I was worried about the threading being too tight, but the brass actually screws on smoothly without any wobble. It's a simple way to share filters between my 67mm and 77mm lenses.
