NiSi Brass Pro 46-49mm ステップアップリング

Went from a 46mm lens to my 49mm filters without any wobble or resistance, and the brass material feels solid enough to last years. It's a tiny piece but it does exactly what it's meant to, no fiddling needed.

The brass threads are buttery smooth when I screw on my 49mm filters, and the step up ring sits flush with no wobble. It's become a permanent part of my kit bag for switching between lenses on the fly.

I was worried about air gaps ruining my long exposure shots, but this brass ring fits so snug it feels machined for my lens. The knurled edge makes it easy to grip even with cold fingers, and it holds my 49mm filters securely without any wobble.
