This is a good set of 2x straightforward, easy to use 67mm to 72mm step up adapters. The adapters fit perfectly onto the front of my Panasonic Lumix S lens. The adapters are made from sturdy metal, and have a very slim profile so are extremely neat additions. The rings are labeled clearly on their sides with size/purpose. Filters or a lens hood connect neatly and remain securely fixed. Come with a plastic storage case and a microfibre cleaning cloth.The only thing I wasn't so keen on was the amount of single use packaging employed: shrink wrap around an outer cardboard box, the two ring adapters individually packed in plastic bags, and the cleaning cloth also in a separate bag.Reasonably priced at £6.49 for the set.

This is one of those pieces of kit that are invaluable and take up no space. Instead of buying filters for all your cameras and lenses, just get step up rings and purchase the largest size filter and then bam, you got filters for all your gear.

These K&F Concept aluminum step-up rings are nice. Sometimes if you screw on a filter too tight, they can be very hard to get off. This happened to me with a 58mm CPL filter, and when I screwed it on, it just wouldn’t come off. After a bunch of turning, it finally came off though. If you’re thinking about buying one of these, the first number is the size of the lens filter threads (usually marked on the lens with a “Ø”) and the second number is the size of the filter you want to put on. Remember: focal length (measured in mm) is NOT equal to filter thread size. I will be purchasing these again if the need arises.

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!

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.

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

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 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.
