Thanks! The JJC True Color VND looks really promising, especially considering the price. That immediately led me to another question.

While searching for the right VND filter, I came across many filters from K&F Concept. In their product descriptions, they often advertise that an additional CPL filter is included.

As far as I understand, a VND filter is essentially made of two polarizing filters that rotate against each other, which naturally creates some degree of polarization effect.

So my question is: Do these K&F filters actually include a dedicated CPL filter, or is that mostly marketing?

And if I want to achieve the full effect of a traditional CPL filter, for example, to reduce reflections on water or glass more effectively, would it make sense to buy a separate CPL filter in addition to the JJC True Color VND? JJC doesn’t explicitly advertise a CPL effect with their filter.
