ProMaster Step-Up Ring 39mm – 52mm

Finally found a step-up ring that threads smoothly without any wobble — the 39mm to 52mm conversion fits my lens perfectly. Works great for using my larger filters on a smaller lens without any light leak issues.

Needed an adapter for my old 39mm lens to fit a 52mm filter, and this ring fits snugly with no wobble. The threads are smooth and it doesn't cross-thread like some cheaper metal ones I've tried.

The machining is spot-on—threads screw on smoothly with zero wobble, which is rare for a cheap little adapter. It converted my 39mm lens perfectly to take my 52mm filters, and has held up well in my bag. Exactly what I needed.
