Customer Reviews (4.4 / 5 · 5 reviews)

Emily N. ★★★★★

Fits my 40.5mm lens perfectly and converts to 46mm without any wobble or cross-threading. The machining is clean and the ring spins on smoothly, which is all I really needed for my filter setup.

Jason W. ★★★★★

Fits perfectly between my 40.5mm lens and 46mm filters with zero wobble. The machining is precise enough that it doesn't add any noticeable vignetting.

Ella W. ★★★★★

Machined threads are smooth as butter, no grinding when I twist it onto my lens, and the step-up lets me use my bigger 46mm filters without any vignetting. It’s a solid little ring that feels sturdier than the cheap plastic ones I’ve had before.
