I love using filters. I find the polarizing filter essential in forests or on the coast. I also love using the ND filter in harsh light, when there are low moving clouds, and in rivers, waterfalls, and on the coast. In situations where I don't need a polarizing or ND filter, I like to use the UV filter to protect the lens.

The truth is that sometimes it's cumbersome to use them, especially in adverse situations such as cold and you're wearing gloves, strong winds, or being very close to a waterfall and spray, etc. I've also left the filter on the lens for a while and then had trouble removing it. So, I thought it would be interesting to try the K&F magnetic filters. I think they're a convenient system and offer a good price/performance ratio.

The package includes a case with the three filters (a polarizing filter, a 10-stop ND filter, and a UV filter) and a screw-on adapter. The case can be attached to your belt to always have the filters at hand. It's quite easy to use. You simply attach the threaded adapter and place the filter on it. Since it's magnetic, it immediately locks onto the filter and won't move. If you want to change the filter, it's as simple as removing and replacing it. You can watch the video where I record the simple process.

The great thing about this system is that both the adapter and the filters are thin, and you can also attach two filters at once, for example, the polarizing and ND filters to capture moving clouds with polarized light, avoiding unnecessary reflections.

In short, I loved the quick filter-changing feature. I'll appreciate it when traveling or in awkward situations.
