Customer Reviews (4.8 / 5 · 5 reviews)

Ryan ★★★★★

Fits my 37mm lens perfectly and the 58mm side grips my filter without any wobble. The aluminum feels solid and the whole thing cost less than a coffee.

Chloe ★★★★★

The threading is incredibly smooth—screws on without any wobble or cross-threading. I’ve been using it to adapt a vintage lens and the fit is solid enough that I’m not worried about light leaks.

Natalie ★★★★★

Switched between two lenses without swapping filters, and this ring locked on tight with zero wobble—the machining is honestly flawless for the price. No light leaks at the seam either.
