Very good quality , easy to use

Pedí el de 82 mm y la verdad me ayudó a mejorar mucho la calidad en mis videos. Para ser un filtro ND tan asequible, es uno que realmente no te deja con las ganas sino que cumple con todo.

Does a good job

I did a quick test. I found the CPL/ND filter to be good. Look at the pictures. Clouds and house are easy to see. You have to find out the exposure time yourself. The setting is great. ND is buttery smooth and so is the CPL. If you take photos by hand and want a good photo of the entire area, this is the right choice.
The price is right and the performance is also great.

K&F combined a circular polarizer with a variable neutral density filter to come up with this excellent 82mm variable fader and CPL as they call it. The 82mm size fits most of my Nikon Z lenses.

It is easy to adjust using the two red opposing tabs on the barrel. A beautiful professional filter at a fair price

Good quality optic and picture comes out great.
Wish it had wider variable range, but works as is well.
I have several K&F filters and they are all good, and this one is good, too.

I had previusly purchased a 50mm CPL 2 in 1 for my other lense and i soon as i bought this 18-150 I had to get this 55mm for it and it feels amazing, and i love it!

The workmanship is top-notch, the thread is flawless, so the filter fits perfectly.
It does what it promises, but the combination is not without its disadvantages.
1. It is thicker and protrudes further than simple filters - as a result, the protective caps, for example, do not fit
2. It is difficult to use, as the polarization is very stiff and the darkening is not smooth either. You will spend the first time finding the right grip so that you do not change the polarization when darkening or turn off the filter when polarizing.

Therefore: if you are willing to invest the time to practice, you get a
2in1 filter for the price of one.
