Riley ★★★★★

The machining on this ring is so precise it threads onto my 40.5mm lens without any wobble, and now my 49mm filters fit perfectly.

Elizabeth ★★★★★

Finally, a stepping ring that screws on smooth and doesn't cross-thread. The 40.5mm to 49mm conversion is perfect for my vintage lens, and it holds my circular polarizer without any wobble.

Joseph ★★★★★

The threading on this ring is precise enough that my filters screw on without any wobble. It's a simple upgrade that makes using my larger 49mm accessories much more practical.
