The K&F filter comes well packaged, even with a storage case. It is well made and looks very good too. In the photo you can see the typical green shimmer that comes from the invisible black dots on the glass. Even a cleaning cloth was included, which I personally always find very nice because you can put it directly with the filter. The filter comes in the 58mm version, which fits exactly. It is easy to unscrew and works perfectly.

The Black Soft Filter is also often referred to as the Black Mist Filter. The filter from K&F Concept is quite good. But what is he actually doing? The filter is there to take out contrasts and scatter light around the points of light. While we see a candle flame sharply and clearly with a short exposure time in a classic image without this filter, one has a so-called halo around the candle when the filter is used. This gives the light a much nicer mood. However, it also reduces contrasts. You always have to keep that in mind when taking the picture. In principle, however, contrast can be easily added again later at the required points. With the 1/4 filter it is also well within limits and it is a balanced effect. Of course you can also create this afterwards, but it's the same as with many other filters. When used front-on, the effect tends to be a little nicer. But it is certainly also a matter of personal taste.

The filter does exactly what it is supposed to. And he does that very well. Unfortunately, I have no comparison to a high-priced filter. Based on my experience, I also think that the difference is only visible if you really take the photos yourself and pay attention to details. For the hobby area, it doesn't always have to be high-end equipment. That's why I give it a full 5-star buy recommendation.
