Promaster Stepping Ring - 52mm-77mm

The machining on this ring is so precise that my filter screws on smoothly without any wobble. It’s a solid little adapter that makes swapping lenses between sizes effortless.

I was worried this ring might be loose, but the precision machining really does give it a secure, snug fit on my lens. Using it lets me pair my 52mm filters with my 77mm lens, which is exactly what I needed.

The threading is smooth and the ring sits perfectly flush against my lens, no wobble or cross-threading at all. It's lightweight enough that it doesn't throw off the balance when I stack a filter on top. Exactly what I needed to bridge the size gap.
