I was looking for a rectangular filter holder for a long time and after a long research I found it at this provider. The holder is supplied with 7 adapter rings and can therefore be attached to different lens diameters. The adapter ring is screwed onto the lens thread and the holder is simply mounted on the ring. The bracket holds securely and gives me no worries that it might not hold even if it has minimal play.

The filter works as it should and comes with a super practical leather cover. A very good alternative to screw-on filters.

You almost always have something to complain about, but in relation to the offered price everything is really okay! The filters are good. I haven't had any discoloration yet. The slot is a bit stiff, but the glasses hold securely. I have nothing to complain about - it fits.

Bought this filter for a music video shoot in Joshua tree and it worked perfectly!! We were able to get beautiful low aperture daytime shots in the desert.

I bought this filter to use in bright sun light with flash without always having to use hss.

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 ...

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!

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.

Does its job, item as described. Clear photos, good lighting. No complaints. And I love that my purchase planted 5 trees! Amazing!

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.
