Like many people, I prefer not to have to buy different filters to fit the different filter sizes for the lenses I own. That can get pretty expensive for high quality filters, like circular polarizers or neutral density filters. Since my lens that uses the largest diameter filters is 82mm, I use step rings to adapt them to my different lenses. I already had a 77mm to 82mm and a 72mm to 82mm step ring, the only one I was missing was a 67mm to 82mm step ring. When I saw the listing for this set, I ordered it right away. I was so pleased to see the low price that I didn't pay attention to the fact that it comes with two step rings!When I realized that it was coming with two step rings, I wondered if I would if they would feel cheap. I have to admit they seem a little lighter weight than my other step ring (also made by K&F) but the don't flimsy and they work very smoothly. They screw on without any binding and my 82mm filters, also, screw onto the step rings smoothly. Not only do you get two step rings for less than you typically pay for one inexpensive step ring but they even throw in a microfiber cloth. This is a real bargain!

As a two-pack, these are a tremendously good deal on two aluminum step-up rings, and coming from K&F I don't really need to be concerned about quality because I know it's there. These are a no-brainer and I'm stocking up to standardize thread size on my old vintage lenses.

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!

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

Always happy with the quality and prices of K&F Concept items, these like all the other items I have gotten from them are top quality and the prices are very reasonable.

I don’t think that I have ever really appreciated step-up rings until now. Currently, I have several lenses with 67mm filter threads, and I wanted to use my new 77mm ND and CPL filters for these lenses. These adapters were ideal for me because they made it easy for me to mount my 77mm filters on the smaller lenses. These have been made from aluminum alloy so they have a very strong and solid kind of feel. No more purchasing several filter sizes for the same camera lenses. Set up takes seconds. I can say with certainty that the quality of the images is not affected in any way. What can be said about the price is that you won’t find a better price for these adapters anywhere. One thing that can now make sense is being able to use my pricey 77mm filters on all the lenses I have. Excellent work that has no sign of any issue when applied. Very impressed. Definitely suitable for interchangeability of different lens filter types and sizes.

K&F has a good reputation for small photographic accessories, and these live up to those. They are basic, lightweight step-up rings. The size is clearly printed on the rim, and they're a good price for a set of two. They don't have any "additional" features, like a textured edge to make it easier to grip, but those aren't necessary with a step-up-- there's plenty of space to grab. They thread smoothly and I like that they're thin enough that the original lens cap still fits (often times they don't with an added ring adapter).

I ordered this 2-pack of K&F Concept 67-82mm Step-Up Ring Adapters to use my 82mm filters on 67mm diameter lenses.Whenever I purchase filters, I always get 82mm so that they will fit my largest diameter lenses. Then, if I am using a smaller diameter lens, I use step-up rings that allow you to attach a large diameter filter to a smaller diameter lens. There are some issues associated with this strategy, however. First, not all step-up rings are created equally. Some are poorly machined and, once attached to your lens and/or filter, are nearly impossible to remove. You may find that the only way to get them off is with a filter wrench, and no one really wants to have to carry a filter wrench in their photo bag. Second, if you are using more than one step-up ring (i.e., 58-62 + 62-67 + 67-72 + 72-22 + 77-82) you may find that you will get serious vignetting, especially on wide angle lenses. You can eliminate the first problem by sticking with better quality step-up rings. You can eliminate the second problem by having just one ring that gets you from your lens diameter to your filter diameter.I've purchased a lot of K&F Concept products in the past, and I have to say that over the years I have seen a major quality improvement. Many of K&F Concepts products are right up there with OEM quality, and this step-up ring is an example. The ring is machined very nicely. The ring screws into my lenses smoothly. It can be tightened securely but remains easy to remove. The same can be said for the threads that the filter screws into. The filter is thin enough to prevent vignetting but holds its shape and does not flex.

My DSLR takes a 58mm thread, while my IPhone lenses were 52mm... This adapts to use my filters on both. Only need 1 set of filters now
