Love the magnetic lens! It works brilliantly and the filter is a nice quality. So far, we are happy with this! A great value and price!

I 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.

Pretty happy with this filter. The magnetic aspect makes it a breeze to pop on and off. No cross-threaded filters or fumbling. The CLP works well and does what it is supposed to do. Diminishes glare and intensifies blue skies. A CPL is one of those filters I never go without, especially for landscape photography. The filter is well-made and finely machined.

I recently received two K&F lenses. I've never used the brand before, although I have heard of them.
I decided to try it on and my my, its a great filter. No issues. Good for shooting through glass or water.
I think the price (very low) has held me back from the brand under the *false* assumption that their filters were less than. Turns out I wrong. They just have great filters at a great price!

I really like the magnetic design of this CPL filter. The filter does reduce the incoming light by about one stop, so it is really nice to be able to pop it off real quick if you need that extra stop of light. I use it quite frequently and being able to remove it without having to screw it on and off each time is a pretty nice time saver. Also, K&F have other filters with this feature so you can hot swap between filters very easily without having to unscrew the magnetic ring section. It's a nice system they've designed. As far as the CPL goes. The image quality is great. Other than the loss of light, which is expected from this type of filter, there don't seem to be any other negative effects on the image. The glass is great quality. I've been using K&F filters for a while now and they all have been top notch. Great brand for photography accessories.

I have never had a single issue with K&F lens filters...so when my decade old lens filter got scratched...I knew just where to go. Fast shipping as always, great quality, good crisp image...what's not to love? Will keep getting them.

I bought the polarizing filter from K&F and am absolutely impressed. This isn't my first filter from K&F and I have to say the quality of the company impresses me time and time again.

The workmanship of the filter is first-class. It feels robust and high-quality, which is not always self-evident in this price range. K&F has once again succeeded in delivering a product that is not only functional but also aesthetically appealing.

As always with K&F, the packaging is very good. The filter arrives securely packaged so that no damage occurs during transport. Everything is very neatly and professionally packaged, which I really appreciate.

A particular highlight is the magnetic attachment of the polarizing filter to the lens. This is ideal for quickly taking a picture without a filter, without having to fumble for a long time. Simply remove and reattach — brilliant!

The quality of the filter is incredibly good. When assembled and you turn it counterclockwise, you can immediately see the change. In this case, the filter minimizes reflections, which makes a huge difference, especially with water or glass surfaces. The colors become stronger and the images are clearer.

Love this company and their products. K&F has never disappointed me. Even on offer today on Prime Day for just 20 euros — I just had to buy it!

Conclusion: The polarization filter from K&F is an absolute must-have for every photographer. It offers excellent quality, is easy to use and the magnetic attachment is a real plus point. Clear purchase recommendation!

K&F continue to make great stuff. Fantastic CPL, seems to work with some other magnetic filters I own

In this range of filters, what I really like is the magnetic system, which allows it to be placed and removed in the blink of an eye, which is super useful when you have to act quickly so as not to lose a good shot. The nano-coated optical glass it is made of offers remarkable image quality, reducing reflections and improving the colors of photos, especially in landscapes.

It's very thin, which prevents vignetting even with wide-angle lenses, a really important advantage. The installation couldn't be easier thanks to the magnetic system, although you have to be careful not to let it fall.

It comes with a cleaning cloth that helps keep it in good condition. It is ideal for both beginners and more experienced photographers looking to speed up their workflow and, above all, a small investment that we will use in the very long term since it is compatible with most lenses, in this case, 67mm.

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.
