These are great step-up rings. I was skeptical based on their price. I have used them with ND filters on Fuji and aftermarket lenses, and they performed perfectly.They fit well together and sit great on the lens. They didn't let any light seep in, and I unscrewed them without any issue. I can't imagine that more expensive step-up rings would do anything differently, and so I'd recommend these as very worthy alternatives.

I have read many reviews about cross-threading and rings getting stuck: I have not experienced any problems: they just work!, Any threaded product will cross thread without due care: from automotive wheel nuts to engine block bolts. I use mine with gentle fingers and take my time- and do not force it onto vintage lenses with out-of-round filter ring threading damaged due to a fall! My only gripe with this set is that it does not have a 49mm ring for many of my 28mm vintage lenses.

There are lots of reviews complaining about the threads. Mine came threaded together half and half. The threads are great, the rings thin, if you tighten them it can be hard getting a grip to unscrew them, but they still come apart without incident. If mine had come cross threaded I would have sent them back, but they didn't and I didn't. They are nicely made, work great, and quite inexpensive.

Look... When you buy filters... It can get expensive. The trick is simple. Since many lenses have different filter sizes you but the largest filter you can... Then get a set of these step down rings to put your larger filter on your smaller lens and save money. This kit has MOST of the popular sizes! A great buy.

I've used the step up filters a few times and all I can say so far is the material quality is great. There is a bit of grinding on some of the filters when you combine them, but other than that they work great!

I know I should have looked more closely but it looked like a complete full step of rings that I thought would work on my 49mm kit lens since it’s my favorite lens, but it does not. Was it supposed to be this way?

I needed a new filter but it was not available for my lens size. Before ordering YET ANOTHER single filter, I decided to purchase a complete set of step up rings. =)While I certainly don't need all of them, it is nice to have the complete set and at $16, it comes out to a bit over $1 each. Might as well get them all at once.Rings are decent quality. Seem to be aluminum. Had no issues getting them on and off from the camera and filters. These are not however high end brass rings, nor do they pretend to be.Only downside versus single packs of rings I bought before is the lack of a nice package or something like a cleaning cloth.In either case, this is a terrific value and I am quite happy with these.
