NiSi Brass Pro 72-82mm opzetring

I was worried about getting a cheap ring that might get stuck, but the precision knurling gives a really solid grip for easy tightening. My expensive 82mm filters now fit perfectly without any wobble, and it hasn't scratched a single thread yet.

The knurled sides give a really solid grip, even with slightly sweaty fingers. Threaded onto my 72mm lens smoothly without any wobble, and the 82mm side holds my filters perfectly tight.

The brass construction is noticeably sturdier than the aluminum rings I've used before, and the knurled sides make it easy to grip even with slightly damp hands. It threaded onto my lens smoothly without any annoying cross-threading, holding my 82mm filters perfectly.
