100*150*2mm Soft GND16 Square Filter HD Optical Glass Waterproof ND Filter - X-PRO Series

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.

Advantages: large, 92 mm polarizing filter, easy to rotate in the filter holder, filters have a plastic frame with a grip lip, practical filter bag, unfortunately only for the square filters, polarizing filters and holder, graduated filter too big. Cons : Filter doesn't seal light properly on holder, there is a 0.5mm gap, only 2 sliding filter slots, filter holder has some play and rattles a bit.
The ND 1000 has a magenta color cast that can be easily corrected in image processing. All in all, the advantages outweigh the disadvantages, I can only recommend it. At Rico Best "Filter Photographer" you can buy a plastic protection, "Filter Guard", there are different sizes, order the right one.

the frames fit super on the 100 normal filter

A bit expensive but good quality, well built

I bought the rectangular filter set directly from K&F.
Since I have worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I have wanted to buy a rectangular filter set for a long time.
Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, as a hobby photographer I was looking for a cheaper alternative.
When I saw several reviews on YouTube, I decided on the K&F set, which is half the price of Haida and CO.
I have absolutely no regrets about my decision.

The filter holder is very valuable and well thought out.
I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel.
The filters themselves are made of optical glass and show no color cast and are also well coated.
Another positive aspect is that the filters have a plastic frame with a tab.
This allows the filters to be inserted and removed without annoying fingerprints.
A bag is included to store and transport the holder and the filters in it.
Also included are various adapter rings for different filter thread diameters.
As a landscape hobby photographer, I no longer want to do without the advantages over screw-on filters.

I give a clear purchase recommendation for amateur photographers and professionals too!
I wasn't expecting such excellent quality for this price.
It's amazing what K&F delivers here.

The system with the CPL filter assembly beats everything I have used so far. Putting on the bracket is also easy to do. The quality of the filters themselves leaves nothing to be desired. This is how filter photography is just fun!

I bought this filter set for landscape photography.

Before that I had been traveling with a screw set from another company. I was then able to screw that onto exactly 1 lens. (I got it to fit a 24-105).

Experience has shown that screw-on filters are only partially usable (in my opinion).
If you use an ND 8x filter, you can safely screw it onto the lens and work with it. However, as soon as it gets higher, the camera is quickly overwhelmed. Set a focus manually, e.g. is an impossibility with a permanently installed 1000x filter.

This set allows you to set up the camera in peace. To compose the picture, to put a focus. Set the polarizing filter. When everything is ready, you can easily add 64x or 1000x and take care of the exposure.

The whole set is incredibly easy to use. Each filter is in a frame, which in turn has special handles.

The set comes in a practical bag.

I don't really want to talk about the space requirements. The screw set is definitely more compact, but at this point handling is simply more important to me.
This set allows me to mount the filters without leaving greasy finger marks on the filter. That's worth more to me at this point.

What I particularly like about this concept is the fact that you can now buy gradient filters and the like afterwards and adapt the set the way you like it.

Absolutely incredible. very happy

This is really a very versatile and high quality system. While the quality is high while the pricing is very competitive compared to other systems. Whenever I have had to communicate with customer service they have always been exemplary.

Very easy to use system. The picture quality is really good as far as I can tell. The polarizing filter works very well. Thanks to the adapter, the filter can be used on any lens. Have never regretted the purchase.
