The K&F Concept 60-inch Invisible Selfie Stick is the same price as the Insta360 brand but you get about 15 inches of more length. Having a longer selfie stick allows for more creative camera shots. The K&F Concept Selfie Stick folded length is 11 3/4" vs the Insta360 stick folded length of 9". Extended length if 60 1/2" for the K&F Concept Selfie Stick and 46" for the Insta360 stick. The K&F Concept Selfie Stick weighs only 1 1/2 oz. more than the Insta360 stick. The K&F Concept Selfie Stick feels very solid and also light weight making it easy to use with my camera. The K&F Concept Selfie Stick takes some effort to extend it to the desired length but I’d much rather have it a little stiff than have it loose and not hold my camera in place. Overall, a great buy.

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.

What more can I say, the Step Up Ring is 1A compatible with my Canon Eos 600D (see picture). It fits like a glove, the zoom can be adjusted perfectly and a polarizing filter can be screwed or clicked on. But does the metal material keep what it promises??? But for around €7 you can't complain :-)

ordered the K&F Concept Step Up Ring 72mm to 77mm to be able to use my 77 filter as well. The ring is cleanly processed and the threads are cut absolutely cleanly, so it can be screwed onto the lens and the 77 filter onto the ring without any problems. No complaints, everything great. I definitely recommend the ring.

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.

K&F Concept Step Up Ring for lenses, 58mm to 62mm, just under 5€ With adapter rings, only the precision of the production counts so that the threads mesh well. The ring from K&F Concept fulfills this very well. Now I can also use the filters from my 55-200mm tele. You should only note that if you leave the adapter on the lens, you may need a larger lens cap, as the smaller one no longer grips. Conclusion: Everything in order, price is right. 5 Stars

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.
