Great for the price, works just like it should but does get stuck very easily. The aluminum its made off is also very soft and marks up really really easily when using a nose pliers over even a very thick cloth to open. K&F could have very easily made engraving on the side like they have on their $100 ND filters, so I highly recommend to buy a filter wrench along with this as there is no way these are NOT getting stuck.

Buy the largest size filter you need and use these rings to adapt to all your lenses. Saves cash. They work.

I have three lenses, and rather than buy the same filters for each, I'm standardizing on the largest, then using the rings to use them on the smaller lenses. I only needed two of the rings, but the kit was inexpensive, and they fit my lenses and filters.

I am a beginner photographer and am taking a class that will be using filters. This was my first time buying step up filters and really didn’t get the difference in quality. They fit fine on my zoom lens but for unknown reasons they will not attach to my two prime lens and I have doubled checked I was using the correct size. Curious if it the filters or my lenses, I bought two breakthrough brass filters and they work fine on the primes. For the price and I need them soon, they are fine for the zooms. But I must admit after buying the brass ones, I will probably get them in brass for the zooms eventually. You can really notice the difference in quality.

A nice set of step up rings… what I do is just buy the biggest ND filters then just used these to fit them to my smaller diameter lenses… they are light weight and sturdy. So just get em.. plus they are affordable

Bought these step-up rings to go with the 82mm ND filter from K&F.Easy to screw on and off, expect to use these rings on my smaller diameter lenses to save cash by not having to buy a filter for everyone.

Pour le prix je pense que l'artisanat est très correct.Il suffit d'être un peu délicat et si vous avez du mal à les dévissé, prenez un gant de cuisine ou un chiffon qui ne glisse pas.Sinon côté produit c'est très propre et très solide vu que c'est très fin.Je recommande

I recently started using ND filters, largely to use wider apertures and slower shutter speeds in bright sunlight. After starting with a filter fit for my smallest lens and adapting it to lager lenses, I grew a brain and now buy filters for my largest lens and adapt them down with these rings! It's important to learn the difference between step-up and step-down, by the way...These are sturdy and easy to use, and I recommend having a set, even if you don't often use filters.

There are lots of reviews complaining about the threads. Mine came threaded together half and half. The threads are great, the rings thin, if you tighten them it can be hard getting a grip to unscrew them, but they still come apart without incident. If mine had come cross threaded I would have sent them back, but they didn't and I didn't. They are nicely made, work great, and quite inexpensive.

These are a MUST-HAVE for your camera and lens kit. No fitting issues, no slipping, and they hold your varying sizes of variable ND, circular polarizers, and much more in place without any fear of them falling off like some other brands do. When you're done using these, they easily unscrew from their secure attachment. I'm very happy with this set added to my filmmaking arsenal.

excelente artículo a un muy buen precio, bueno para aquellos que necesitamos unos adaptadores para filtros y no estar gastando mucho dinero en comprar un filtro para cada diámetro de lentes

中国のねじ工場の暇な時にどっかでつくらせたんでしょうが、制度も仕上げも悪く、日本製のレンズやフィルターに組み合わせると傷だらけになります。ゴミです。買ってはいけません。
