Everything as described. A great system.

easy assembly, easy handling, the CPL filter can also be easily screwed in and out.
CPL can be easily adjusted when assembled (filter holder in front and filter pushed in).
Overall, the system makes a very good impression. All in all a very good purchase and clear recommendation.

I haven’t had to use it at this point since I use a slow ISO film to begin with. Will use it in the future though I am sure.

Great set of filters for those who cant or dont want to get Lee filters. No colour cast but i would recommend getting some nice pouches to protect them

It's actually a great system:
The filter that comes with it is very well made and, in my lay eyes, has no color cast. The filters are tight, but not too tight, the clamping device for removing the filter system works well and the adapter rings that come with it are also good...

Overall, I'm satisfied and have now gotten more filters from K&F Concept.

Very well packaged and finished!

For a while I had hesitated between several brands to choose a filter holder for ND and GND filters. I used a flash sale to purchase this kit. I'm not disappointed.
The set is sturdy and easy to store.
The rather pretty body has 5 compartments, 3 of which are raised via a ribbon for square ND filters. There is a belt loop and a belt loop on the back of the case. I would have liked a slightly roomier compartment to house the adapter rings with the CPL filter when that is removed.
The assembly (or disassembly) of the elements is well explained with instructions in several languages, including French.

Main positive points:
No dominant color, no loss of sharpness in the first tests performed.
The plastic frame with its tabs for handling ND filters.
The system for installing the SPS filter on the filter holder.
the knurled knob for mounting the adapter ring and rotating locks the filter holder.
The easily accessible wheel for controlling the polarizing filter.
The stable hold of the square filter on the filter holder.
The robustness of the metal filter holder.

If you must find some negative points: hold
the square filter in the filter holder a little too tightly.
The click is too loud to lock the CPL filter in the filter holder.
No bag to independently protect the CPL filter in the housing.
No protective cover for the CPL when the set is installed on the lens.

After many reviews that I looked at on Youtube, I decided on the new K&F filter holder and have not regretted it so far. It is easy to use and makes a very high-quality impression. The use of the CPL filter is a great solution. Lever up, put it in and lever down again, done. Adjusting the wheel is also buttery smooth. In contrast to the first K&F filter holder, the filters, which now have a frame, can now be pushed in very easily. Not too easy and not too heavy either. A clear buy recommendation.

I loved the quality of the materials, all metallic. I looked at many kits but they were all plastic and this one caught my attention especially with the comments. The truth is that it was a success because every other similar kit doesn't fall under 300€.The nd1000 optical filter is made of glass and gives a very good quality. The only thing I noticed is that it loses a little saturation and the white balance is a little bluish, but when processing the RAW it is easily fixed. You increase the colour temperature and saturation and you're done!!! (I use a Canon 80d + 16-35 f4 is). I imagine every lens will be different.Attached a few photos so you can see the difference with filter and without filter. Exposure time on the photo with the 30" filter.If you want to start in the world of filters, don't even think about it for this price. Excellent results.

It's made from really high quality leather and has a magnet to keep it closed. There is a belt loop which I will probably never use, but there is a metal frame to clip onto your bag which I will probably use.
