It has a good quality and is super finished. The leather bag is very stylish and protects the glass. Got it because I had previously bought a cheap one that had a little purple stitch. But this is perfectly no color cast or anything like that. It darkens the sky super and I would buy it again and again. Back at any time

I'm impressed by the quality.

Fast delivery. Good and nice packaging
There are many different connector adapters for all common lens sizes. The bays were a little too tight on delivery, but I unscrewed the screws a little and then it was ok. I didn't notice any color cings in the filters which I like

Delivery was very quick. Unbeatable for the price... Everything is of high quality. I can also not confirm some criticism that the gradient filter is less foggy towards the middle. Been cleaned up for me. If the slot is a bit difficult, then loosen the 4 screws on the filter holder a little bit and everything runs like butter!!! No color cast on the filters! Great bags included... polarizing filter history, simply screw an existing one onto the lens and then the filter holder on it. What more could you ask for without having to spend €400-500 right away... Full marks from me.

bought the filter bag to have all the filters at hand more quickly and not to have to search for them, and to save space. The bag is of high quality and fits perfectly for 100x100mm filters. A total of three (theoretically four) different filters can be stowed in it. So it is perfect for a standard ND filter set (8,64,1000). The inside of the bag is completely lined with microfiber so that the filters can be transported in it without additional protection. As a smart feature, it has a pull-out mechanism. This means that if you open the bag and pull the tab, all the filters are offset and highlighted so that you can grab them much better and read the name directly. I bought another glass filter at the same time - ND64. Since I already own an ND8 from another brand and the ND1000 from K&F, this was of course still missing in the series. Overall, I am super satisfied with the quality of K&F. The filters (update 2020) have almost no color cast anymore. In certain light situations, my ND64 filter turns green. However, this can be corrected without major problems during image processing. The shape of the filter (no round filter) also means that there are no problems with vignetting or falling sharpness. The images are therefore almost unaffected in terms of image quality. The processing is top (no sharp edges, stains, etc.) and the price speaks for itself. All in all, I'm very happy with the entire filter system from K&F and will probably get hold of the gradient filters soon!

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.
