NiSi 黃銅專業升級環 49-58mm

The knurled sides make this step-up ring surprisingly easy to grip even with cold fingers, and the brass build feels solid without being too heavy. I’ve had no light leaks or wobble since attaching it to my lens.

Finally, a step-up ring that doesn't get stuck on the lens—the brass construction slides on smoothly and the knurled edge gives me plenty of grip even with sweaty fingers. It feels solid enough to hold my heavier 58mm polarizer without any wobble.

The knurled sides make a real difference when I’m swapping filters in a hurry—no more slipping. This ring threads onto my 49mm lens perfectly and holds my 58mm filters securely without any wobble.
