Promaster Step Up Ring - 37mm-49mm

Needed this to attach a 49mm filter to a 37mm lens, and it fits perfectly without any wobble. The aluminum construction feels solid enough for regular use.

The machining is spot-on—it threads on smooth with no wobble, and the 37mm-49mm jump feels solid when I swap lenses. Took me two seconds to seat it, and filters screw on just as easily. Exactly what I needed for adapting my older glass.

Threads onto my lens perfectly without any wobble, and the aluminum construction feels solid. It’s a simple, well-machined ring that does exactly what it’s supposed to do.
