These filters are an absolute highlight, convincingly good quality, everything fits perfectly, everything is high-quality and securely packaged and safely protected for transport in beautiful cases. The first tests are promising, but I currently don't have a suitable motif to test the full strength of the filters, but I'm absolutely confident that excellent and convincing pictures can be taken with them.

This is already my 2nd gradient filter from K&F, I still have the GND 0.8 and am very satisfied. Simply unbeatable for this price. I can't see any color distortion.

You can see the result nd64 and gnd8 soft process in the pictures... The whole system is simply great

I've been toying with the idea of buying a gradient filter for a long time, although the prices from Nisi, Haida, etc., around 150 euros, have always put me off. Then I came across the filters from K&F, because the filters were reasonably priced, I ordered them. The extremely beautiful and high-quality packaging should also be emphasized. Here you get an imitation leather case that is lined with fine fabric on the inside and has 2 magnetic buttons incorporated. This case is again in a nice padded cardboard box, very valuable and stable so I wasn't really disappointed. Filter holder: First of all, it has to be said that you need a filter holder system for the filters, which costs around €25 at K&F. This is well made and serves its purpose. Here comes the filter holder in a padded cardboard box. The scope of delivery includes the filter holder and 8 adapters in the size 49mm - 82mm. So I'm already looking forward to going out into nature with the filter to test it. The adapter ring is screwed onto the lens thread and the holder is simply mounted on the ring with a snap mechanism. The mount holds securely and doesn't give me any concerns that it might not hold even with minimal play. The optical quality of the gradient filter is great! I didn't notice any loss in image quality and there's no distortion or vignetting. Furthermore, I could not detect any color impairments or other color distortions. The filter does what it is supposed to do, it easily darkens an overexposed sky and saves me a lot of work in post-processing. Conclusion Since I haven't worked with ND filters before, I don't know what I could complain about here. Overall, I am very satisfied with the glasses from K&F. You get a high-quality, processed filter with top optical quality and a good scope of delivery (artificial leather case). For the price of around €89, it doesn't need to hide behind the other brands. I will soon buy more glasses from K&F.

was really looking forward to it, everything is packaged beautifully and with high quality, so you can't say anything really great. I'll try the filter out today at the nearest lake. I watched a lot of videos and reports before I ordered the filter. Nobody mentioned that the adapter rings in the RECORDING have quite a bit of play. That's not so bad, but it bothers me a little personally. I have to come up with something like me that can fix. Otherwise, everything is top made of metal, only the mounts for the plates are made of plastic, but these were screwed on, which means you can dismantle them and theoretically make your own out of wood. I'll try to optimize the system for myself. I can recommend it for beginners and for testing.

am a passionate landscape photographer as a hobby and have now switched from the screw filters to this rectangular filter system from K&F. The screw filters were all fine, but you don't have the option of attaching a graduated filter to the ND filter in order to achieve even nicer effects. It is mounted on the lens using so-called adapter rings, which are included in the most common sizes for lenses. After attaching the adapter ring to the lens, the filter holder is attached. This is secured by a small lever (spring-loaded) and later released again with this. Now you can slide the filter plates into the filter holder. This lifts a bit severely but it should also hold and must not wobble. It is also important to observe that the filter used is close to the lens so that no more light can penetrate between the filter and the lens, which could possibly ruin the recordings. In terms of quality, the system makes a good impression considering the price. The only thing I noticed negatively is that the filter holder has some play after it is placed on the adapter ring and why there is no adapter ring for a 55mm filter diameter in the set, I also ask. 55mm is a common diameter for lenses. I can highly recommend the K&F system for amateur photographers. The professionals will probably use filter holder systems from other manufacturers, but they also cost a lot more.

I've been using the product for about half a year (almost daily) and I'm very happy with it! Pro: The installation is easy and holds very well and with the installation rings it can also be used universally for every lens! The filter also keeps its promises and the quality is still excellent! Contra: the glass is a bit difficult to slide in, if you want to push the filter in, you should remove the attachment to avoid damaging the thread! Conclusion: I am very satisfied with the product, even if you have to be a bit careful! I give this product 8/10
