Hannah ★★★★★ Oct 21, 2026

The machining on this ring is precise—threaded onto both my lens and filter without any wobble. It’s a solid, practical solution for adapting 46mm accessories to a 40.5mm lens.

Ryan ★★★★★ Oct 20, 2026

Finally got this to use my 46mm filters on my 40.5mm lens, and the machining is so precise there's no wobble at all. The matte finish keeps it from snagging on the filter threads.

I was a little worried about stepping up from 40.5mm to 46mm, but the threading is precise and smooth—no cross-threading at all. Works perfectly with my filters.
