Promaster Stepping Ring - 43mm-52mm

The threads are cut so cleanly that attaching my 52mm filter to the 43mm lens took zero effort, and it stays perfectly snug even after a full day of shooting.

Screwed onto my lens without any wobble or play, which was a relief after some cheap adapters I've tried. The black anodized finish matches my gear perfectly and feels solid. Exactly what I needed to step up my filter size.

The machining is precise enough that it seats flush without any wobble, which is exactly what you want for a step-up ring. Only gripe is the knurling is a bit smooth when your fingers are cold, but it does its job perfectly.
