Promaster 7375 52-72mm ステップアップリング

Finally, a step-up ring that doesn't cross-thread on the first try—threaded onto both my 52mm and 72mm filters perfectly. The brass ring feels solid and hasn't gotten stuck, which is a relief after cheaper aluminum ones. Exactly what I needed for my filter collection.

The step-up ring threads smoothly onto my 52mm lens and holds the 72mm filter securely, with no wobble at all. It feels solidly built and the brass threading is a nice touch for durability. I've used it on several shoots and it's held up perfectly.

I needed a step-up ring to use my 72mm filters on a 52mm lens, and this one fits securely without any wobble. The aluminum build feels solid enough for regular use.
