The filter does what it should, it extends the exposure time. So far, I have not been able to detect vignetting or incorrect color reproduction. And so I am satisfied. The packaging of the filters is very good and practical, something that some higher-priced filters cannot do that well.

I like the quality of the materials. They are all made of metal. I've seen many kits, but they're all made of plastic, especially this one because the comments got my attention. The filter is made of glass and the quality is very good. The only thing I noticed is that it is losing a bit of saturation and the white balance is a bit bluish, but it's easy to fix when processing RAW. They increase the color temperature and saturation. If you want to get into the world of filters for this price, please don't think about it. Excellent results.

Very good quality ND1000 K&F Concept filter, including glass filter, filter holder and lens adapter for the filter holder. Since we have a large number of different diameters, the adapter ring enables us to place the filter holder on every lens. They are ferrous metals and well made. Each ring has an inscription of the corresponding diameter. The filter is housed in a leather case with a thin paper inside. The shell is strong enough to properly protect it. With its price, it's a great filter to experiment with and get great results. I am really happy and enjoy it a lot. I recommend it to you!

It's my first ND filter and I'm totally satisfied, it's made of glass and looks good. I've used it with my Sony A6000 and haven't seen any too noticeable dominance or aberration. It comes with a leather sheath that is lined with a soft fabric inside; Velvet type that is practical to be able to carry around without fear of scratches.

I bought the filter bag, on the one hand, to have all the filters at hand more quickly and not have to search, and on the other hand, 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 covered with microfiber so that the filters can be transported in it without any further protection. As a smart feature, it has a pull-out mechanism. This means that if you open the bag and pull the tab, all filters are highlighted offset so that you can grab them much better and read the name directly. At the same time I bought another glass filter - ND64. Since I already have an ND8 from another brand as well as the ND1000 from K&F, this was of course still missing in the series. Overall, I am very satisfied with the quality of K&F. The filters (2020 update) have almost no color cast any more. In certain light situations my ND64 filter goes slightly into the green. However, this can be corrected without any 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 workmanship is great (no sharp edges, stains, etc.) and the price speaks for itself. The filters (2020 update) have almost no color cast any more.

Fast delivery. Packaging of the glass in a high quality case. Unfortunately, I haven't been able to test filters yet, but I've already bought several. Was very happy with all of the filters. Price performance top.

Excited to use this on an upcoming cross country road trip as well as at a summer job in coastal Alaska. It’s affordable, eco friendly and packaged to travel safely.

About the filters Perfect quality, no color cast. The leather bags are stable and protect the filter plates. Of course, I didn't want to test scratch resistance, but it should be many times better than with plastic filters. The sharpness is not affected. The filters fit very well in the holder. The holder is stable and, thanks to the pusher with which it can be removed, can be removed very quickly, which can be helpful if, for example, you want to check the focus again. Thick +, because all ring sizes are included and not every ring has to be bought ...

I was excited to get this 43mm lens filter as it's hard to find a good ND filter for that size lens. The filter is built well and works great on my Fuji cameras. Look no KF if you need a 3 or 6 stop ND filter.

Overall, the set makes a very valuable impression. The adapter rings are made of black anodized aluminum - they are well made, not sharp-edged and the thread can be easily screwed onto lenses. Apart from the filter inserts, which are made of plastic, the filter holder is also made of black anodized aluminum. Here, too, the workmanship is excellent. Perhaps the quality of the plastic inserts could be a tick better, but that is already lamenting at the highest level. Packaging was perfect; Adapters are packed individually; The filter holder is in a nice, padded cardboard box.
