Promaster 7382 52-77mm ステップアップリング

This little ring lets me use my 77mm filters on my 52mm lenses, and the threading is smooth as butter—no annoying cross-threading issues. Exactly what I needed for my kit.

Finally, a step-up ring that actually screws on smoothly without that horrible grinding feeling. The threads are perfectly machined and it holds my 77mm filter securely with no light leaks.

Picked this up to use with my 72mm filters on a 77mm lens, and the threads are clean and precise—no cross-threading or binding at all. It’s solid metal and feels like it’ll last through a lot of swaps in the field.
