NiSi Brass Pro 49-77mm 升階環

This brass ring is noticeably sturdier than the aluminum ones I've used before—it threaded onto both my lens and filter smoothly. No wobble or binding at all, which is exactly what I needed for my 49mm lens to take 77mm filters.

The knurled sides make all the difference when you're swapping filters on a cold morning with gloves on—no slipping at all. The brass frame threads on smoothly and doesn't bind like the aluminum ones I've used before. Solid little piece that's worth the extra weight.

This step-up ring fits perfectly and feels solid; the brass construction is noticeably more durable than the aluminum ones I've used before. It threads on smoothly without any wobble.
