Review on K&F Concept 18-Piece Filter Ring Adapter Set, Camera Lens Filter Metal Stepping Rings Kit - Black (Includes 9-Piece Step Up Ring Set + 9-Piece Step Down Ring Set) by Robert Moloney

After getting them two things have become clear to me: 1) I will never use most of them. 2) They really aren't the best quality. Some of them had cross threads that I was able to make and fix, and luckily those rings weren't ones I would ever use. Please note that if you have a metal lens, use a brass ring instead of these metal rings. Metal on metal has a bad habit of bonding. I pressed down on a flat silicone baking sheet to get even pressure to unscrew mine from the lens. This is PIA, if it happens on site and you don't have a flat meter and silicone gasket. to help you remove the ring. Think about what you need - if it's all about a one size ring, just get a better version of the ring you need and you'll be a lot happier. As for buying, because you just want to know you have a whole bunch of cheap ring adapter tools - in case of Armageddon or an alien attack - then they're great for spares/other junk in your camera parts basket. and you will be much happier.
