K&F Concept 67-82mm(2 Pcs) Step-Up Ring Adapter, 67mm to 82mm Step Up Filter Ring for 67mm Lens Install 82mm ND CPL UV Lens Filter

What an affordable, solution to my running off and buying a filter that didn't fit my camera. In seconds I stepped up from 58mm to 77mm, everything worked and problem solved. Quality materials, smooth, tight threads, simple solution. Saved myself a lecture about my shopping habits.

This step-up ring works exactly as intended. It screws on easily and lets me adapt my lens thread to fit my ND filter without any issues. Since step-up rings are inexpensive, they’re a great way to save money—you don’t need to buy multiple filters for different lens sizes. Simple, effective, and cost-efficient.

I recently picked up this 55mm to 67mm step-up ring adapter, and it works exactly as advertised. The build quality is solid — made from durable metal (not cheap plastic), and the threading is smooth and precise. It fits perfectly onto my 55mm lens and allows me to use my 67mm filters with no issues at all. No cross-threading, no light leaks, and no vignetting. It’s a simple but essential piece of gear if you're looking to expand your lens/filter compatibility without breaking the bank. Highly recommend for any photographer or videographer needing a reliable adapter!

Awesome set of step up rings they do the job perfectly and for an awesome price can’t beat! I use it to step up my phone adapter to use with my bloom filter and they work so well that it almost looks like it was part of the filter adapter!Only thing I wish it had would be grooves to make removal easier, but I have yet to have these step up brings get stuck like other step up rings I’ve bought from other suppliers so amazing no issues yet after two months of using :)

While I think the value of these step up rings are amazing, I don't think the same could be said about the quality. They seem to be very well made, but at the same time don't function properly.In my case, I have the Sony F 1.8 11mm lens which has a filter size of 55 mm and bought the K&F nano x true color VND at 67mm. After purchasing the 55 mm to 67 mm step up ring, I found out that the step up ring tightens nicely onto the lens, but not at all on the filter itself. No matter how much I tried to tighten the filter on, it would always remain loose.For a normal ND filter, this wouldn't be that big of a problem, but since I had a VND, I was unable to utilize the lever on the filter since the entire filter itself would rotate. This meant that I would have to use two hands to control the VND filter. I tried using both step up rings to see if one was just defective, but they both had the same results.After purchasing a much more expensive step up ring that was made out of brass, the issue went away.TLDR; if using a VND filter, the connection between the step up ring and VND will be loose, unsecure, and freely rotating.

This step up ring adapter fit on both my camera lens and filters perfectly. Smooth screw on motion. A great value for the price!

Excellent quality, fits perfectly, good construction, a necessary tool if you have several lenses and need to use your filters with all of them.

I have not had any thread jamming issues with K&F step up rings. The reason may be that in their front threads I mount K&F magnetic adapter rings. Having threads cut in the same factory may be important since filter manufacturers have not standardized the depth of their threads across their industry.These step up rings are thin and are economical.
