K&F Concept 77-82mm(2 Pcs) Step-Up Ring Adapter, 77mm to 82mm Step Up Filter Ring for 77mm Lens Install 82mm ND CPL UV Lens Filter...

I used these step up rings to fit a SmallRig Mini Matte Box Lite on my Sony E-Mount 50mm f1.8 and Sony E-Mount 35mm f1.8 lenses. Theyre good quality and a great value. I cant justify paying more money for step up rings from a different brand. Just get these!

The product works as advertised. It is a quality product.

I use Canon EOS cameras and originally I tried to stick with lenses that took 77mm filters. That worked for a while until I started lusting after a Tilt Shift lens and got myself a Canon TS-E 24mm lens which has a 72mm filter thread. I really don't want to buy 72mm filters. K&F CONCEPT to the rescue! This pair of adapters rings (I got 72mm to 77mm) are packaged just like you would expect a fancy modern high end filter to be packaged. It's just as good as an expensive Circular Polarizer that I got recently. There is a smart outer cardboard box and then inside is a nice hinged filter box which each of the rings individually cellophane envelopes. A ring like this is a tiny thing that you have to squint at closely to inspect. But when you do you that, you realize that these rings are very beautiful indeed. I mounted a ring on my Tilt Shift lens and the 72mm thread was super silky smooth and could not possibly be any better. Then I when I fitted the 77mm filter to it, that 77mm thread was just as gorgeous silky smooth as well. On top of that the weight of each ring is very very light. I bet they weigh less than your lens cleaning cloth. So there is no reason to not put them in your camera bag. They might be the lightest camera accessory of all time. Fabulous! There is something about cameras and lenses, especially from the highly respected makers, that highlights how beautiful engineering can elicit a visceral and tactile love of machine in us the users. Sometimes I find myself caressing my camera body it is so lovely. And these rings from K&F CONCEPT slot into that aesthetic without even trying. They have an understated but very classy loveliness about them that any camera addict could not help but love. Totally amazing and highly recommended!

Packaged in a plastic box for protection and in sealed envelopes. I have 43 to 49mm step up. I pulled out my new ef m 22mm lens, it has a 43mm filter size. I opened one of the envelopes and threaded it into the K&F uv I have on the lens, it threaded smoothly and silently, no looseness. Then I pulled out my 49mm cpl and then threaded it onto the step-up ring then I turned the cpl outer lens continuing on to the right to see if it will lock and I can't get it off. At first the cpl locked so I unthreaded the ring and the cpl off and tried to get the cpl off; got it off. Then I turned the cpl to loosen it up and tried again. This time all threaded well with no lockup. All unthreaded nicely. No issues, no problems. I tested the second ring and all threaded well. Then I threaded the ring directly onto the lens and then screwed the cpl onto the ring and it threaded perfectly and no locking, perfectly unthreaded off the ring and the ring off of the lens. Wonderful. I had a size issue with this order and I contacted K&F and they resolved it immediately. Absolutely wonderful company to deal with. Their products are excellent, do the job without hassle and if there is an issue K&F handles it superbly. These rings are a value and thank you K&F for the towelette gift. They work great. By the way, "K&F Perfect" is a phrase I created because they are "perfect".

nothing bad to say, great value. works as you'd expec.t
