It took a few minutes to figure out the menu system and buttons but once you figure it out it’s easy. The selfie screen is really cool while you’re in the water. Photos are good, and I attached a couple taken. Happy with it and it will become the go to vacation camera. Waterproof for sure!

I have not yet been able to justify using a more expensive filter system like Lee. I live near water and like longer exposures to smooth out the water for sunset shots. This makes the trick perfect for my use.

Lifesaver when I dropped coins under the sofa - magnet saved the day!

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!

I have the K&F magnet system on all my lenses and, in addition to the Black Mist, I have several of the appropriate ND and CPL filters here. They're so handy, easily stackable and the connection is strong enough that I don't have to worry about one of them falling off. The black fog effect is very low here and is only really noticeable with a lot of backlighting. Many cheaper filters often have a color cast, but I didn't notice that at all with the K&F.

The only downside is that with my Sony lenses, at least the included magnetic caps are really hard to pull off when you have the lens hood on the lens (either forwards or backwards). A grippy element on the front of the cap would have helped. I could 3D print a holder and glue it there to fix it. As the caps aren't really the main reason for using a magnetic filter system although I still give 5 stars they would have been a nice bonus if they worked well but they aren't really critical to the product.

In summary, I liked that the system was able to change the filter so quickly when I was traveling or in awkward situations, I would appreciate it.

The magnet system is just easier and faster to use when adding or removing filters. The glass seems to be of high quality and I really liked what K&F Concept did with these filters.
