Good robust quality, threads easily into respective smaller or larger adapter rings. Works well with my Nikon D7200, would highly recommend.

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.

Does what they are meant to and has saved me many times. All I'd say is sometimes they screw together very tightly and can be difficult to seperate. Still worth buying.

Very handy stuff and helps a lot. The quality is pretty good. The only thing i miss with these rings are up to 105mm. There are only one problem with these rings: It can be stuck in each other and hard to remove, so be careful when you are tightening the rings, or else you can get a really difficult task to release the ring from each other. I have tried lots of these rings, but K&F Concept has the best quality and i recommend this mostly.

Ok

Prompt dispatch and well packaged. Photo projects can proceed at pace now. An excellent product, well made. Thank you so very much.

My downstep 52-49 /55-52 came jammed in my 58-55/62-58 , disappointed with that since it seems I'm not able to remove and use them properly, all the rest works fine.

I like the principle of these step-up rings, and they certainly perform as intended. They scale any of my lenses up so that I can use a single set of 77mm filters across all my kit. There's no noticeable vignetting, they're built and finished nicely and ultimately work.When combined with screw-in filters, the process of switching sizes, lenses and deconstructing your setup after use can be tedious and fiddly. Some rings will lock together more firmly than others, making it difficult to remove the rings correctly (instead removing too many or too few). Worst case, you end up with one ring still on the lens, at which point it's a fight to remove.Having said that, if you still want to go down the route of getting step-up rings as opposed to a filter holder, these fit the bill.
