52-55mm Step Up Ring Aviation-grade Aluminum Filter Adapter Ring 2-pack with a Cleaning Cloth
SKU: KF05.335
Let's say you have a pair of lenses with a certain diameter and another pair with a different diameter. For example, I have three lenses with a diameter of 77 mm and one with a diameter of 67 mm. What do you do? Do you buy all the dual filters? You can also make a 77 polarizer and a 67 polarizer, so you leave it on, but if we go to the ND filters, we can't buy all the dual ND filters. After spending a lot of money on a dual polarizer, a dual UV, a dual ND8, my brain finally starts working and I think: why not buy an adapter ring and avoid buying two ND16s, two ND64s, etc.? I'm a genius. Obviously, you have to take the diameter from the smallest to the largest, so I got a ring that, mounted on a 67, allows me to use 77 filters, and that's it. Perfect, no compatibility issues, precise threading on both sides, negligible cost, and a lot of money saved.

This is my third K&F purchase and once again very pleased with their product. Unlike other adapters I have, these screw on and off just like a quality filter. My others are difficult to thread on, bind up and one only screws on half way.These are precision made and at a great price to boot. I also need 55-52mm step down and I will be buying K&F for those also.If you got stuck with some grindy junk adapters in the past, try these, I think you'll be glad you did.A+++ all the way.

Let's say you have a pair of lenses with a certain diameter and another pair with a different diameter, for example I have 3 lenses with a diameter of 77mm and one with a diameter of 67mm. What do you do? Do you buy all the double filters? A 77 polarizer and a 67 polarizer can also be done, so then you leave it up, but if we go for the NDs we can't buy all the double NDs. After spending a lot of money on a double polarizer, double UV, double ND8, finally my neuron starts to work and I think: why not get an adapter ring and avoid buying 2 x ND16, 2 x ND64 and so on? Genius that I am. Obviously it must be taken with the diameter from smallest to largest, so I took a ring that mounted on the 67 allows me to use the 77 filters, and voilà, that's it. Perfect, no compatibility problems, precise threading on both sides, negligible cost and a lot of money saved.

67mm to 88mm step up rings x 2I was surprised with the size and weight of these step up rings, because, they come in a protective filter type box , rather than loose.The filters are metal (Aluminum I think, as per the title, not brass as it says in the description)At first glance the full kits of step up filter rings look to be good value , however, in use I prefer these because a single ring is lower profile than stacking several and I don't need to store all the extras rings .Having a set of two works well because I prefer to leave the step up ring attached to a 82mm filter (ND and CPL), rather than a lens, because the step up ring prevents the lens hood and the lens cap fitting.Good price for 2 metal step up rings , just get the size you need . 5/5 recommended

I ordered the K&F Concept 72-77mm(2 Pcs) Step-Up Ring Adapter so I could use some 77mm filters on my 72mm lenses. The step-up rings are exactly what I needed, and the quality is what I have come to expect from K&F. The rings are made of machined aluminum, and they thread perfectly onto the filters and the lenses. They come nicely packaged in a plastic case, and a lens cleaning cloth is included. A lens adapter ring is a fairly simple product, but a cheap one will make life difficult because the adapter ring won't thread smoothly onto the lens or filter or will stick once it has been threaded on. These rings do not have either of those problems. And to top it all off, the adapter rings are an incredible value for such high quality rings. I will definitely buy more of these if I need them, and I highly recommend them to anyone in the market for lens adapter rings.

I have a phone cage I no longer use as I have no filters that fit it, in an attempt to be a cheapskate I ordered this as I do have the larger size filters.What I didn't take into account was that once fitted it meant any filter I tried to screw on was blocked by the red adjustment knob pictured.I can get around this by adding further step up rings but that isn't quite the elegant solution I had hoped for.The product itself is well machined and fits the existing 37mm thread like a glove, so no complaints there.
