NiSi Brass Pro 52-77mm ステップアップリング

Finally, a step-up ring that doesn't get stuck—the brass frame threads on smoothly every time. I've been using it with my 77mm ND filter on a smaller lens, and the grip is solid.

The knurled sides make unscrewing it effortless even with sweaty fingers, a huge plus for me. The brass construction feels solid and threads onto both my lens and filters without any wobble.

It’s rare that a step-up ring feels this solid, but the brass frame and knurled sides make it easy to twist on without any of the sticking I’ve dealt with before. Screwed my 77mm filter onto my 52mm lens and it sat perfectly flush, no wobble at all.
