I admit that at first, this 3-in-1 filter generated skepticism in me. The idea of ​​combining Black Mist, VND, and CPL in a single filter seemed strange, perhaps impractical. I thought, 'Aren't I paying for something that forces me to use all three effects all the time?' And I know many professional photographers share this idea, but the truth is, when analyzing my outdoor workflow, I realized something important. Typically, to achieve similar effects, you can use the three filters separately: ND or VND, CPL, and my favorite, Black Mist. This is not only cumbersome, but it can also lead to vignetting, internal reflections between glass, and the like.

That's when I understood the clear idea behind this K&F design. A 3-in-1 filter that's very convenient for situations where I need a lot of light control, glare reduction, and a soft Blackmist effect (for those who don't know, this is when it breaks up only the highlights, gently spilling them out, making the image more organized and less electronic). It's suitable for photographing waterfalls, rivers, waves, or light painting scenes, as well as for shooting sequences with actors or models in sharp highlights on clear days. The CPL eliminates reflections, the VND controls exposure, and the Black Mist softens glare.

The construction is super solid; for me, it's a high-quality filter that simplifies your equipment and allows you to capture stunning images. The system for adjusting the ND and adjusting the CPL by tightening the screw really seems amazing to me. Although we have individual filters for each effect in the production company, I recognize the value of having an all-in-one solution for certain types of photography and video, where the Black Mist is often essential. In this case, the Black Mist value is 1/4, and I usually use 1/8, but when combined, it's not as obvious. I like it.

I recommend it because it's a versatile, high-quality filter.
