Using on my NIKKOR 70-200mm. No image quality degradation. Strong magnet holds the filter well, and it's not coming off the lens when taking photo. I have multiple K&F filters, and they are all good quality. Recommend!

I've been shooting with 35mm cameras since I was 16 years old and that was 56 years ago. I have a collection of cameras I use and lots of accessories including filters that I can use across my camera collection. I've always found changing filters while shooting to be a pain. Screwing them on and unscrewing to remove them. It takes time and coordination. Then about a year ago I was introduced to magnetic filters. Magnetic filters remove the need to screw on and off the filters you are using. There is an adapter ring which screws on to the front barrel of the lens and the filter's outside rim is magnetized so instead of screwing the filter on and off it mounts and adheres to the adapter magnetically. To replace filters you just need to pull off the filter to be removed and pop on the desired filter. No screwing needed. I'm sold on them. I now have magnetic adapters for each of my main lens diameters and am slowly replacing my conventional filters with the magnetic filters. Most brands of magnetic filters are compatible with each other so you can mix and match. I've been buying K&F concepts filters for a long time. I'm confident in their quality and I know that they stand behind their product and for the price, you can't go wrong.

view a CPL as a "just-in-case" type filter. So I usually have one in my bag but seldom use it. I guess I like the reflections in a lot of cases, especially in street photography. Perhaps if I did more nature photography I would feel differently. So the fact that this has a magnetic ring is just perfect. That way I can just snap it on when I need it. It doesn't seem to like a lens cap, but I really don't use those either, as I have a decent UV filter on there all the time and occasionally shoot with a hood. I am using this on my 24-105mm S on my S5IIX. With this stacked on a UV filter I still see no vignette at the wide end, which is what I was hoping for.

This polarizer lens is great, it helps with water (or oily faces)! Easy to install and remove on your lens, and the thread is perfect.

like my K&F Concept 58mm Magnetic Circular Polarizer Lens Filter. It fits well magnetic or screwed in place. The quality of the filter is very good. It also takes a lens cap securely to protect it when not in use.

This has been my go to filter as the magnetic attachment makes it so practical

Superbe produit de qualité Je recommande vraiment

Arrived yesterday, tried it immediately, it seems excellent, I will test it better on Saturday..

Well constructed, easy installation and simple to use.

I used to use screw filters. These magnetic filters are more convenient to use.
