Breakthrough Photography 77mm to 82mm Step-Up Lens Adapter Ring for Filters, Made of CNC Machined Brass with Matte Black Electroplated Finish

Fantastic quality! Great threads, brass construction. Easy to remove from the lens because of the grippy construction.A good filter is money well spent... You get a 2k+ camera, a couple of thousand dollar lenses, and then put a 20 dollar piece of glass on it. You get what you pay for. These filters are right up there with B+W, HOYA.

I needed to get step-up rings so that I could use larger 82mm filters with lenses that had smaller filter size threads. I found these to be the highest quality option available. The knurling on the sides is easy to grip, while the brass is excellent material for this task.

I purchased a inexpensive ring flash and some closeup lenses (the kind that screw in front of your lens) for a project. The ring flash uses adaptors that also screw into the lens, but they are made of plastic and not threaded on the inside. The adaptors for the flash weren't able to screw far enough into my filter or close up lens to not deform and fall out.As I was under a time crunch, I found a work around by not using the flash, however knowing I would want to use the flash at a later time i looked for an answer, then it hit me an adaptor ring might work.The cost of the Breakthrough item was double the price of others, but it was made from brass and in the USA so I bought it.It arrived today and boy howdy it was so well made and packaged it took me all of one second to know i had made the right move, well worth it.By the way, this adaptor cost almost as much as the ring flash but I will be using it way after that flash bites the dust.Great product, thank you

The best Step-up brass ring

Works well

Absolutely quality product from Breakthrough photography. I have used their filters and other products and this one is the same consistent quality.

Breakthrough Photography's step-up lens adapter ring is firstly made from brass and not aluminum. Just like B+W's filters which are made from brass, this is important because brass expands and contracts at different temperatures than aluminum. In essence this adapter ring will stay true to form better than an equivalent aluminum one, allowing you to easily attach and remove it and not have the dreaded stuck filter syndrome whereby the filter you have attached to your lens has expanded or contracted just enough that you can no longer remove it (at least until the temperature has normalized again).Living in the South where we have long hot summers, this is important to me and one of the main reasons I thought I would try this step-up adapter.The adapter has an electroplated black finish to it so that it fairly much matches your lens and this is harder to scratch and look bad. It also helps with weathering making this weather and corrosion proof.Breakthrough Photography's adapter also has a ribbed outer edge which is excellent as it gives you much needed grip making it very easy to screw on and off your lens and also for when you are attaching and removing your filter.The main reason I got this adapter is that I have a bunch of filters for my Canon 24-70IIL lens which takes a 82mm filter, but I also have the Canon 100-400IIL and the 70-200IIL lenses which take 77mm filters. This step-up adapter would allow me to use my 82mm filters on my other L lenses removing the need to buy separate 77mm versions of each filter (which are over $100 a pop aren't exactly cheap). I tested this out this weekend with the solar eclipse. I have a 82mm ND10000 solar filter which I wanted to use on my 100-400 lens. It worked flawlessly. The filter fit fine, with the ribbed outer edge I could very quickly remove the filter during totality and quickly screw it back on once totality finished. It worked a charm.I realize this is slightly more expensive than the cheaper aluminum step-up filter adapters but it is thoroughly worth it.

I ordered this step-up ring in hope to find out if it's really as good as ppl say and if it will solve the binding issue I had with *every single step-up ring* I bought so far.The short answer is: Yes.The longer answer:Usually I make sure I don't screw a filter all the way into a step-up ring, so it's easier to remove it. However, when working with C-PL, I usually end up with the filter getting screwed tighter and tighter as I use it more and more with a step-up ring. The result is that most often than not, I find myself struggling to separate the two, even with filter wrenches.With this step-up ring, the first thing I did was to take my C-PL filter and screw it all the way in and see if I can unscrew it using my hands. Each time I screwed it tighter and tighter. So far - I have no problems unscrewing the filter, even when it's screwed into the ring as tight as possible.To sum it up:This step-up ring is a little heavier than the others I've had, the ridges on it are a great feature as it gives you more grip for separating it from a filter, it's definitely well made, and (most important) it's doing exactly what you expect it to do without the risk of binding with your filters.
