52-67mm Step Up Ring Aviation-grade Aluminum Filter Adapter Ring 2-pack with a Cleaning Cloth

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 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.

These K&F Concept 43 to 49mm step-up rings take your lens' 43mm filter thread and convert it to a 49mm thread so that you can put filters from your 49mm collection on it. It is not just about not having to pay for another set of filters though, adding some extra diameter to the filters means that you are less likely to get vignetting caused by the edge of the filters coming into shot with wide angled focal length lenses such as 24mm or 28mm focal lengths or their equivalents.
These step-up rings from K&F Concept are made from aircraft-grade aluminium alloy so they are not as soft as pure aluminium and therefore harder-wearing. These are well made and perform their job perfectly well.

2 pieces of step-up rings from K&F. Well built and pretty lightweight.
The product descriptions say they are brass and seem to come with a non-slip design, however, they are not. So keep that in mind.

Came in a box. The hard plastic case is of good quality. Rings are made of aluminum/ metal as described. Matte black finish. No dents or chip off on the rings. I used this on my canon lens 58mm to fit my 67mm filters as this is a 58-67mm step up ring. It came 2pcs so I have a spare ring.

Impressive for the price. The 49mm - 55 mm fit my ancient Pentacon 1.8/50 exactly and easily screwed on
There are two stepping rings, a microfibre cleaning cloth and a plastic case in the pack.
Both rings are sturdy, thin and professionally finished. The case is big enough for more than two rings separated with tissue paper and the size marking on the ring allows for easy identification.

This item is a set of two step-up rings. I now know the dimensions, and the terminology (step-up / step-down) work from the camera outwards, i.e. towards the subject. They arrived in a sealed package, with the description clearly shown, so I could check it was the correct item before opening. Each of the two rings was packaged separately in a clear plastic bag, and their dimensions are clearly marked in white text against the black anodised surface. I will NOT mix these up easily. There is also a vacuum packed microfibre cloth. The whole set is in a larger plastic storage box, which is very robust. The threads on the rings, both internal and external, have been manufactured to acceptable tolerances, and fit my filters and lens with reassuring precision. The after sales support is exemplary, with replies in less than one working day, from a named individual.
