ProMaster Step Up Ring – 43mm-49mm

The threading is so smooth I didn't have to fight it at all, and the 43mm to 49mm conversion fits perfectly on my lens. It's a tiny upgrade but makes a big difference for using my larger filters.

Finally found a step-up ring that doesn’t cross-thread or wobble; the precision machining makes it feel solid when attaching filters. This 43-49mm size fit perfectly on my vintage lens, so no light leaks or alignment issues. Exactly what I needed for a clean setup.

Went from a 43mm to 49mm filter setup without any wobble—the threading is buttery smooth. Really solid build quality for the price.
