have a DJI Osmo Action camera, early version, and next to the Go Pro the colors of the grass, blue skies etc. seems a bit washed out. I love the deep blue sea and sky, and the lush slightly deeper color in the lawns; that is exactly what this filter gives you. It comes with a magnetic ring. Be sure to order the right size, or have an adapter set that will enable you to use it on different lenses. The magnetic base is included so you can swap it out/take it off in a millisecond, and put it back on the same. Overall quality is superb. Not much you can say about a filter that does what it is supposed to do, and does it very well. Highly recommended. PS: Getting it out of the tight-fitting box is a bit of a nightmare if you like to keep the compact fitting box intact. With all of the information on it, it makes it easy to identify what it is in your camera bag. Oh well, what comes out in the film is all that matters.

Not yet well tested but does its job for the little I've used it so far. It attaches well to the lens and if you want to leave it on, the lens cap clips on well. The filter seems to be well attached to the ring. Satisfied with this purchase, arrived as expected so perfect for me so far. I would recommend

Got this for my Fuji 100-400 AF and works a treat , a little pricey for the brand ,but does the job

I bought the K&F Mark CPL filter holder as a replacement for the MK 2, which was quite cumbersome to remove and install the polarizing filter. The magnetic polarizing filter is now easier to change.
There are 5 stars for the entire system due to the good price/performance ratio.

Great polarizing effect, strong magnet. Couldn't be happier. Bought the 77 and 82mm for my RF 15-30 f2.8 and RF24 - 100 f4 landscape lenses.

Included in the package is everything you need to use the magnet system and more, in fact you will find:
- the CPL filter (Circular Polarizer)
You must have the magnet ring or protection filter on the lens (one of the two of your choice) assemble and then you're ready to replace the filters in seconds without the risk of damaging the front threads.
The magnetic cap allows you to connect it directly to the magnetic ring, protective filter or polarizer filter.
The quality of the filter is excellent and the polarizer is easy to rotate, it does not have the classic frame of polarizers, which over time are either too hard or too light becomes. Simply rotate on the magnetic base and stay in place smoothly.
The magnetic system is strong enough not to drop filters and even mistreat everything, replacing filters is always easy, precise and above all very fast!
