Do exactly what they should, good quality and excellent value.

Very good product and very good quality

I like the principle of these step-up rings, and they certainly perform as intended. They scale any of my lenses up so that I can use a single set of 77mm filters across all my kit. There's no noticeable vignetting, they're built and finished nicely and ultimately work. When combined with screw-in filters, the process of switching sizes, lenses and deconstructing your setup after use can be tedious and fiddly. Some rings will lock together more firmly than others, making it difficult to remove the rings correctly (instead removing too many or too few). Worst case, you end up with one ring still on the lens, at which point it's a fight to remove. Having said that, if you still want to go down the route of getting step-up rings as opposed to a filter holder, these fit the bill.

Very handy stuff and helps a lot. The quality is pretty good. The only thing i miss with these rings are up to 105mm. There are only one problem with these rings: It can be stuck in each other and hard to remove, so be careful when you are tightening the rings, or else you can get a really difficult task to release the ring from each other. I have tried lots of these rings, but K&F Concept has the best quality and i recommend this mostly.

Fantastic value for money. Great quality metal rings with fantastic threads.

Great set of converter rings step up and down easy to use,easy storage

The goods match the photos

Works great. Very useful for my lenses.

Great product. I use it all the time with my 85mm 24-105mm, 70-200mm. I recommend it.

Der Filteradapter Set läßt sich einwandfrei verwenden.

Just what I needed.

Benutzt die Adapter um meine Filter auf Objektive zu montieren. ICh besitzt nur Filter in den Größen 77 mm und 82 mm und verwende diese, dank dieser Ringe hier, auf ALLEN meiner Objektiven. Die Ringe scheinen gut verabeitet zu sein, es kommt nur selten zum verhaken dieser. Mein kleintes Obketiv hat einen Objektivdurchmesser von 37 mm, wenn man diesen bis zu 82 mm erweitert kommen die Ränder der Ringe aufs Foto. Daher empfehle ich bei zu größeren unterschieden was den Durchmesser angeht, speziell eigene Ringe zu kaufen, die einige zwischengrößen überspringen. Die Adapter lassen sich wunderbat mit anderen Ringe kombinieren.

High quality and works very well!
