I love K&F and this is a quality filter. The feel is premium. The movement is very smooth. And it even comes in a nice slim case that looks like felt and leather. I have all of these filters separately but this is the first time I got them all in one. The good thing is, there is no vignetting, so that is the advantage of having them all in one relatively slim and light filter kit like this. However, it just makes for a pretty fiddly setup when you are trying to get shots. I realized I needed to step down the light first, then adjust the CPL. Often I would do this out of order because the light would change, and then I got the wrong angle on the CPL.

Also, it is a lot to also have the mist diffuser in there. But that may just be my shooting style with a mist. I like to blow out the bright light sources with it, especially with things that are edge-lit. But combining it with these other filters just made it harder to expose my shots properly overall.

I think the best case scenario for this is landscape photography, specifically moving water like a stream or waterfall.

The pics I attached are not great. But they are straight out of my S5IIX with a 24-105 F4. Just to give you an idea of what you are working with.

Overall I understand why you would want a nice set like this for some cases, but it is not as versatile for my personal shooting scenarios. I was hoping for a one-filter solution to take on a vacation. I may still bring this because it is so compact, but I would probably also bring my 3 separate filters.

Just a note, don't worry about the orange knob unscrewing and falling off. It seems like it will but it just gets loose and does not actually come off unless you unscrew the tiny screw inside of it.
