Promaster Stepping Ring - 72mm-67mm

The threading fits perfectly onto both my lens and filter without any wobble or cross-threading. It’s a solid little adapter that feels much more durable than the plastic ones I’ve used before.

The machining is so precise that my filter screws on butter-smooth with no cross-threading at all. I've been using it daily for a week and the fit hasn't loosened up at all, which was my main worry with a step-down ring.

Picked this up to use my 67mm polarizer on a bigger lens, and the aluminum feels solid with no wobble once screwed on. No light leaks or weird vignetting in the corners either.
