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.

Good product for the price, enables me to use the same filters on many different lenses and save some money in filter purchases

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.

They are good and serve me well. I have many filters all 77mm size, I have used these adaptors to fit my filters to 67mm and even 49mm lenses, it works well for the purpose. However, they don't screw on lens very easily, you have to align and realign many times until you get it right, something that never happens to me when I am using my decent quality Hoya and B+W filters (I think I saw somewhere that aluminum is not a great material to make precision screw mount, expansion with heat would affect alignment, so you'd expect this from cheap quality stuff made to serve basic job, brass would cost way more which is what is used in B+W filters). I would recommend these except in two cases: you need to use them constantly, or you can't afford fiddling with these during an important shoot (please note I am a hoppiest not a professional so my advice is based on my needs).

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.

These work great to step up or step down. Using more than one at a time though can create vignetting.
