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.

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.

I loved the quality of the materials, all metallic. I looked at many kits but they were all plastic and this one in particular caught my attention from the comments. The truth is that it was a success because any other similar kit does not fall below 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 bit of saturation and the white balance is a little bluish, but when processing the RAW it's easily remedied. You increase the color temperature and saturation and you're done!! (I use a Canon 80d + 16-35 f4's). I imagine each optic will be different. Attached some 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, for this price don't even think about it. Excellent results.

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.

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!

Far exceeds expectations. Quality of packaging matches a much more expensive purchase. The visual quality of the filter is equally top-notch. After using the filter in my filter holder, I can see no evidence of color cast or filter clarity. Overall, I have nothing but great things to say about this offering. Will definitely look to this manufacturer for future filter purchases.

I received the new X-PRO filter set today and have already tested its applicability in the apartment. I'll give you a verdict on the quality of the filter glasses and how they can be combined in one shot... The box supplied holds the holder + adapter rings + CPL + ND 8/64/1000. The compartments can be pulled out on the drawstring and the filters can then be removed very easily. The plastic filter frames are discreetly sharp-edged, but not uncomfortable, and allow the filter to be removed and handled without having to touch the glass. Thanks to the tabs on the frame, the filters can also be pulled out of the holder very easily, especially in any order. I ordered two empty frames in 100 X 150 from the manufacturer's website, which should hold my graduated filters, which I have from another manufacturer, upon receipt. I'm curious how well this works. If it works, then I have a complete system for myself, with CPL, three ND filters and two graduated filters (Soft 0.9 and Reverse Soft 0.9). Sliding the filters in and out of the holder requires some force, but isn't awkward or imprecise. In this way, the graduated filter will also be easy to align. The handling of the CPL filter with the insert bracket is great, the turning mechanism is a bit rough, but precise. Screwing the adapter rings onto the lens works very well, the threads are cleanly worked, so nothing rubs. Attaching the holder to the adapter ring is also a joy and the presence of a set screw is very welcome as the holder rotates on the ring with relative ease. The handling of the system has already convinced me, I can live well with "only" two slots for my needs and I'm looking forward to the first use, in the next few days, in the great outdoors and with cold fingers. So far I've worked with round screw filters and dispensed with gradient filters, which I would like to change now. I also looked at the system from Rollei (Mark II), which cannot keep up with the handling of the X-PRO from K+F. Everything is very flat and fiddly, offers hardly any contact surface for holding and assembling the parts. Getting the polarizing filter or adapter ring out of the holder is no fun and almost impossible with cold fingers. K&F solved this much better. If you want to use gradient filters, the X-PRO set is a good choice. If you only need gray filters, I would recommend a magnetic round filter set with a diameter that is significantly larger than your largest lens, which is even faster to use, is more compact and should then do not darken with several filters in parallel.

I was really looking forward to it, everything is packaged beautifully and with high quality, so you can't say anything really great

Great value for money!
