I like the size of this one, and K&F has good quality filters(depending on the tier they can be really good or ok). that I also use for my cameras. I have the Tamron Sony lenses and they use 67mm so it's nice and fit nicely with those along with others. This is perfect because I use this in conjuction with a step up ring on my phone with this phone clip for my filter sets and I can get some awesome filter fx. I have some gradient and ND filters. I've also used one of my variable NDs 67mm on the phone with it. Another way to have fun with photography without all the gear.

They screw on pretty smooth it have a quality threads, and it work just fine. Perfect for someone who's only going to be casually using their step up rings, I am a professional photographer & I was looking same filter Ring Adapter & I order this product which is very helpful for me when I use multiple filter with my Nikon 5300 camera lens. During photo-shoot many time we have to change camera lens along with filter also, so using this ring it is very helpful for me, these rings get there job done, and don't get stuck. Please note - these are step-Up rings also have Step Down Rings total 18 rings.

The Step-Up Converter Ring was packaged well and shipped quickly. So far I'm pretty happy with the build quality. The ring is made entirely of metal and seems sturdy to me. In addition, the internal and external thread is properly worked. Thus, the adapter can be easily screwed onto lenses. With the help of the adapter ring, I can now easily use my larger ND filter on my smaller lens. Everything works without any problems, which is why I can finally recommend the adapter ring.

Normal step up ring that works

K&F Concept Step Up Ring for lenses: filter adapter ring made of metal for ND, polarizing filters, etc. Good quality, workmanship and price. The adapter can be screwed on and off my lens without any problems. The filter used also turns gently on and off.

Custom-fit step-up ring, which also has the right quality and feel

received this product as a free trial as part of the Vine program. Thanks very much. I tested the 72mm to 77mm version. I use the ring on my Viltrox 85mm f/1.8 II, which has a 72mm filter mount, to use my 77mm polarizing and gray filters. The filter ring is processed perfectly. It is easy to screw in, and a filter can also be easily screwed into it. Releasing a filter from the ring requires a bit of finesse, but the ring can't help it. What would be nice: a box so that it doesn't bend in the bag during transport. But since the competition doesn't have that either, I won't deduct a star for it.

I have mounted the kit on a lens with the 72mm ring and it fits perfectly. It is easy to assemble and its handling is very simple, it does not require reading the instructions (I would say it is better not to read them) just looking at the illustrations is enough. Regarding the quality of the product, it seems to be made with good materials and the finish is excellent; The polarizing filter holder is very effective, placing the filter well and carefully, you do not touch it at all. There are two compartments for the square filters that I hope to get the most out of, I'm happy. As for the optical quality of the filters, I can't give an opinion because I haven't used them yet.
