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.

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.

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.

The set is the perfect introduction to the world of filter systems! If you want to try your hand at landscape photography or who "only occasionally" do landscape photography, you will not be able to avoid the set. It is solidly built and even a stay of several weeks on the beach did not affect the filter, the posture or the adapter rings.

As advertised. Would have liked a better case given I travel with them. However for the price they’re adequate. I haven’t used the glass yet so I can report on performance.

The filter holder is made of aluminum and is very well made and fits perfectly. The delivery was very quick and the filter came in a sturdy, padded box.

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.

Fast delivery. Very robust packaging. Great leather bag with magnetic closure. Filter looks robust and high quality. Filter without scratches and stains. An update will follow after the first use.

I bought it on the spur of the moment because it was cheap, but it works reasonably well.

Sunglasses for the lens. First class.
