NiSi Ti Pro 55-62mm 鈦金屬升級環

I’ve been using this step-up ring for a week, and the titanium build feels much more solid than the aluminum ones I’ve tried before—no threading issues at all. It’s slim enough that my 62mm polarizer still rotates smoothly on my 55mm lens.

Finally, a step-up ring that doesn't get stuck on my lens—the threading is smooth and precise. I've been using it with my 55mm prime and it holds my 62mm filters securely without any wobble. Was worried about it adding bulk, but it's incredibly thin and lightweight.

The titanium build feels noticeably more solid than standard aluminum rings, and it threaded onto my lens without any binding. I've been using it to pair my 62mm ND filters with a 55mm lens, and the fit is both snug and easy to remove.
