DANGER!!! This review covers both the installation kit with the ND1000 filter and the GND8 soft filter that I purchased together.

After looking at competitors and trying brand names, I found these at a fraction of the price without compromising on quality. The entire user experience from delivery is exceptional. They are very much buying a high-end product without the overpriced name brand. I bought these to help with my landscape photography and they work exceptionally well with my Sony A7III. The camera practically sees at night, getting a long exposure without this filter was incredibly difficult, I would often have a very split image, with the moon/sun very bright at the top and everything under the sky in complete darkness. After using the occlusion filter, any additional adjustments were made in a snap. The material feels very sturdy, although I don't plan on testing the limits, I believe it is scratch resistant. I'm looking forward to sunsets to test this further.

Of course very good, I've been taking long exposure photos for years.
There is no dominant. It is of excellent quality.
I've used round filters and square gradients for years. To this I give a 10 for 52€, which is the same quality as the ones I used from 150€. And I say it with knowledge of the cause. Amazon excellent, on time. Delivery at 9:30 in the evening (the first delivery attempt was at 12:30 but I wasn't home, they made the effort to get it to me before 10:00.. very good!!

For the price of Lee filters and holders, I decided to try the K&F kit. The quality of manufacturing and packaging feels top notch and with the Morning Landscape Reverse Grad ND filter I didn't notice any adverse effects.

am very satisfied with the optical quality of this filter. Especially in comparison (eg with Cokin) it proves that you don't work with a plastic toy. The transitions are smooth and not immediately (frighteningly) noticeable

Finally a graduated filter that does NOT cost a small fortune and is still high quality. No scratches, well packaged in the included bag and fits my M10 filter system!!

The filter pack is well made and designed to be protected. The filter removal system is practical, pleasant to use and useful for controlling the high tones of the sky, etc. In my opinion, it will be very important to choose a metal filter holder that precisely blocks the mounted filters.

I've been thinking for a long time if I should get this filter. Ultimately, however, Amazon has no risk and can test them.

Pro:
Top packed.
Glass filter which is evenly coated.
Leather bag.
I find the bag better than the chunky boxes such as Lee or Haida

Negative:
slight but really very slight colour changes on the edge.

I'm going to get the other filters to test.

I bought the filter bag in order to have all the filters on the one hand faster and not to have to search and on the other to save space. The bag is high-quality workmanship and fits perfectly for 100x100mm filters. A total of three (theoretically also four) different filters can be stored in it. So it is perfect for a standard ND filter set (8,64,1000).

Inside, the bag is completely covered with microfibre so that the filters can be transported without further protection. As a smart feature, it has a pull-out mechanism. That is, when you open the bag and pull it on the tab, all filters are highlighted offset so that you can grab it much better and read the label directly.

I have added another glass filter at the same time - ND64. Since I already own an ND8 from another brand as well as the ND1000 from K&F, this was of course still missing in the series. I am on the whole super happy with the quality of K&F. In certain light situations, my ND64 filter goes easily into the green. However, this can be corrected without major problems during image processing. Due to the filter form (no round filter) you also have no problems with vignetting or sloping sharpness. The images are thus almost not affected in the image quality. The processing is top (no sharp edges, stains etc.) and the price speaks for itself.

All in all, I am very satisfied with the entire filter system of K&F and will probably hit the gradient filters soon!

Box contents:

- ND64 filter 100 mm x 100 mm
- synthetic leather case for filter 100 mm
- padded cardboard box for filter case

Very high quality 100 mm x 100 mm ND64 filter with a measured thickness of 1.85 mm.
The pictures look very promising even with sharp fixed focal lengths — it's fun to take pictures. For me, there is no reduction in quality due to the filter. Also
noteworthy is the extremely beautiful and high-quality packaging. Here you get a faux leather case, which is lined with fine fabric inside and has 2 magnetic buttons incorporated. This case is in turn in a beautiful padded cardboard box.
Haven't worked with ND filters yet, but I don't know what I could complain here. The price is also extremely fair in comparison. Therefore, full score and recommendation on my part.
