The rings are great if you own different diameter lenses which I do. I buy filters for the largest lens and use the rings to fit the filters to the smaller lenses so far no problems.

I have had many products made by K&F and I have found them to be well made and sold at a competitive price these step up rings are in that category, well made with quite a deep thread to ensure if careful no damage to your camera lens or filter.

Does exactly what it says it does. Rings can sometimes be a tiny bit fiddly to line up the threads (we are talking minor set backs) and the paint they use isn't exactly scratch resistant but for the price I can't complain.Handy tool to have in your camera bag, managed to utilise some filters from my old olympus camera and use them on my canon with these.

What I have enjoyed from using these rings is that it seems very easy to stack them and they retain a very fluid movement when tightening or loosening them. They do nto seem to cross thread and so far no lubrication has been needed. They are complete with no duplication or missing rings.The build quality seem good and they are marked up and easy to read.Very impressed with their quality and non sticking threads.

Most low-cost step-up rings, including those I have owned in the past, are very poor quality. They typically have roughly-cut threads that bind with filters so that it's very difficult to get them apart - usually requiring a filter wrench. That wastes a lot of time in the field. These K&F step-up / step-down rings, however, are very good indeed. They're strong, well-finished, and they don't bind anything like as much - no filter wrench needed.This set contains all of the major sizes for most DSLR and mirrorless system lenses, and when you work out the cost per ring, they are a bargain. Much better value than buying individual rings.

This is an extensive set of filter adapters, 9 step up and 9 step down. Not the cheapest, but excellent quality, much better made than some I have previously purchased. Rings can be combined, but beware if you combine rings you may get some vignetting.

Fantastic quality and idea.I'm not sure how many of these I will use but wish I had years ago. It is just something every photographer should have 'just in case'At least I will be able to find my 'step down' and 'step up' converters now.
