Promaster 6665 Reverse Ring - 72mm Canon

The threading on this reverse ring is surprisingly smooth and precise—it clicked onto my 72mm lens with no wobble. I’ve already used it for a quick macro shot of a coin, and the detail was sharp. Definitely worth the low price for a simple adapter.

Putting this ring on my 72mm lens was a breeze, and the metal threads felt sturdy even when I tightened it. I took some test shots of a coin and was impressed by the clarity right to the edges. A simple way to get into macro photography without buying a dedicated lens.

I was able to get super sharp macro shots of a coin by flipping my 50mm lens around with this ring, and the 72mm threads on both sides made it easy to attach. It's a solid, no-frills piece of metal that does exactly what it's supposed to do for close-up work.
