I have quite a few K&F products such as the filters, sensor cleaning kits, battery charger and adapters. Their products have turned out good for me and I have been using them for years. This adapter came in a lens filter box along with three pieces of microfiber cleaning cloth.
The quality of this step-up ring is great, it is made of brass and it is lightweight. I got the 49-58mm adapter so that I can use my 58mm filters. The adapter installed easily on my Canon RF-S 18-45mm and was easy to remove as well. My 58mm UV, ND & CPL filters installed nicely on this adapter. Now I need to get a spare 58mm lens cap as I don’t want to leave my other lens without the cap.
Happy with the product. You can find a similar metal adapter at a much lower price but it may not be brass.
I normally get a semi-inexpensive aluminum adapter to live with each of my filters that needs one. I have a lot of filters and almost always use 67 mm lenses, so I don’t want to have to keep track of whichever adapter I need and have to switch it around. Why would someone like me get this fancy brass one, then?
1) Brass is better for extremes in temperature, since it resists expansion/contraction issues more. This is rarely a worry for my shooting, though.
2) But brass is less likely to get cross-threaded or deform. So if you’re using it a lot, or maybe aren’t careful, brass can be better.
3) So that’s good for me, but honestly, the knurled parts on the edge are the most useful part for me. Aluminum step-up rings also come with knurled (ridged) edges in nicer versions, but once you’re spending more on that, you want to consider whether the cost of brass makes more sense for you.
My use case is replacing the step-up ring on my Lensbaby Omni filter system. I use it more than any other filter, so my reason (2) applies (frequent use, cross-threading resistance).
It’s also really easy to unscrew the Omni adapter from its step-up ring, and then I have to unscrew the step-up ring separately and waste time. Reason (3) comes in here, because the knurled parts make it way easier to grip the step-up ring, unscrewing it from the lens and keeping it with the Omni adapter.
The only con to me is that brass is heavier than aluminum. That’s significant when you’re talking about holding a camera for a long time, but for me, the pros definitely “outweigh” the con.
Trying out this brass step-up adapter through the Vine program hasn’t convinced me I need all my filters to have brass adapters, but I’m very happy to have it for my main use.
I have a good-sized collection of vintage prime film lenses which I frequently adapt for digital photography/video. So, step-up rings are a must, and I’ve learned over the years that the brass ones are much better over the long term than the cheaper aluminum ones.
I also have a good-sized collection of lens filters and accessories from K&F, all of which I’m happy with. So I expected this to be of high quality, and I wasn’t disappointed.
This is a high-quality step-up ring, made of quality brass and well-finished. It does what it needs to and will last a lifetime with proper care and handling. Very pleased.
This adapter ring is great, it is the correct size and fits my camera well. I am quite pleased with the quality, it is solid and heavy, not cheap like some adapter rings that I have seen. Works well and having an edge that has a grippy texture to it make it perfect for my use.
You can definitely feel the quality once you take it out of the box! Heavier, thicker, and really holds itself when used on a lens.
I really love the anti-slippery frame design that is not found in other cheap step-up rings. With that, taking it off from a lens becomes much much easier! Highly recommend it if you are looking for quality step-up rings!
I found some 77mm IR lens that I wanted, but have a 52mm lens, so I found this. It works well. The way it’s made when I screw it onto the 52 the adapter does not interfere with the lens itself.
This is a great step-up lens filter adapter ring. I have no problem screwing onto my lens and my filter. The quality of the materials is particularly good and seems very durable. Although K&F is not the most famous brand in the industry, the quality seems to hold up well against B+W and other well-known brands.
I am pleasingly surprised how light weight this adapter is which is a good thing. It does not feel cheap at all.
However, it is a thin design. It is a bit difficult to remove the adapter. Be sure you bring your filter wrench with you.
Overall, good adapter.
I managed to damage an aluminum step ring that connects a filter holder to my lens, so I decided I’d upgrade to a brass version. This is a quality step ring from K&F Concept and is indeed a step up from my previous adapter. Brass is superior to aluminum and way better than plastic.
I also appreciate the included lens cloths… nice bonus!
As with most K&F products this step-ring is well machined and designed smart. The ring has nicely knurled edges for easy mounting. It easily fit my 58mm, allowing me to borrow filters from my larger 77mm. It comes in a fancy plastic storage box with sealed microfiber cloths that are handy in the field.
