The filters are sufficient for my purposes - amateur photographer - and the quality is good. What more could I want?

New camera, new lenses so I thought I'd also go for new magnetic lens filters. K&F had these at a reasonable cost and so far I am liking them very much. Great brand.

The kit is complete for my needs, the UV filter is unnecessary since it has the magnetic ring and I would add the 10-step filter.

The filters you must have in your camera bag
High quality product

I tested the filters briefly and couldn't find anything negative.
Tested with: Sony a7cr and Sony G Master 16-35 2.8.

Extremely practical. You wonder why you didn't buy this type of magnetic filter before.

Finally, you don't have to run after filters that you can't install with cold fingers. Really good. The bag is great too!

Excellent quality filters and very easy to apply to lenses.

The filters from K&F-Concept are generally very popular, especially in terms of price/performance, and this magnet set follows on from that.
As a set with CPL, ND8, ND64, you are definitely equipped with the most common filters. Even if the ND64 is not enough, you can of course stack the ND8 on top without any problems and darken it even further. Of course, this is not as good as using a stronger ND straight away, but given the quality of the K&F filters, this is honestly justifiable, as flaring and color shifting are not a big problem here.
I think it's great that a magnetic lens cap is included. Especially if you use this set with other magnetic adapters for other sizes, you can forget about the normal lens cap. With the magnetic cap, however, you are very flexible here.
The magnets hold together really well, but you can still get the filters off. They are almost a little too strong, but it's better that way than if you can remove the filters very easily and they fall off quickly; that would be much more annoying and impractical.

A small bag is also included in the delivery. The bag is not bad, with a magnetic flap and then a zipper. Good combination, so you can close the bag completely when you put it away or don't need it that much at the moment, but if you are changing a lot, then you just leave the zipper open and just close the magnetic flap. For my taste, however, this could be a little stronger, I would be a little worried about losing the filters.

There is nothing negative to say about the quality of the filters, the coatings give a high-quality impression and are highly recommended for my circumstances.

I also think it's great that the back of the filter has no thread, so that it can be magnetically attached and removed without any problems. The front side is equipped with a thread, however, so you can still use non-magnetic filters that you may have.

All in all, a great set.
The price is of course not exactly cheap, but in my opinion it is still justified, especially if you can then use the set with the respective magnetic adapter on different lenses.

Installing the filters is super simple and quick, which allowed me not to waste time on site. The photos with and without the filters are day and night, especially for the reflections on the water and the sky effects. The only downside is the price which stings a little at first, but given the quality of the images, I don't regret my purchase. On the other hand, for those who like to control everything via their phone, there is nothing like it here, everything is manual.
