Brand Story

Natural Night

The distinct filter is designed to block the wavelengths of light created by mercury vapour, sodium and other Low CRI lights that are often used as streetlights. These lights are usually yellow/orange and are the primary cause of light pollution around cities. This makes capturing beautiful nightscapes near cities very difficult.

Multi-layer Anti-reflective CoatingTo Remove Light Pollution
If you are an ight photographer then you almost certainly have run into the horrible yellow glow of light pollution or the ugly yellow cast that street lights spread over urban nightscapes. This light pollution and yellow cast can hide stars and mess with the white balance of your scene.
Without Natural Night Filter
With Natural Night Filter

Keep far away from light pollution when enjoying the wonderful night

As you can see there is a significant difference in the yellow cast caused by the lights of the city. You also have an increase in the contrast of the image, especially in the areas that were washed out by strong nearby street lights. But you will also notice that you have a more magenta sky. Personally, I prefer the magenta sky over the yellow/green sky. But that is also an easy adjustment in post-processing.

Nanometer Coating
The night filter is a glass filter that is coated with a double-sided multi-layer waterproof and oil resistant coating. This reduces ghosting and flaring and also prevents the natural oils on your skin from sticking to and smearing the filter.

Price Performance top
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.

Super addition to K&F filters (e.g. ND64)
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!

Convincing ND64 Rectangular Filter
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.

Finally my first gradient filter
I have long played with the thought of buying a gradient filter, whereby I admit prices around the 150 euros have always quenched.

Ultimately, I chose a sales filter from K&F, much cheaper and I would really not be disappointed!

Beautiful transition and
high-quality glass
= high-quality workmanship.

The filter does what it should, it darkens an overexposed sky easily and saves me so much work in the post-processing in Lightroom.

Highly recommended!

Graduated filter Soft for beautiful photos
I bought the Graduated Filter because it was recommended to me by friends.

After a few weeks in use, I can say that I am more than happy with it.
When photographing, it is necessary to darken the sky (e.g. at sunrise or sunset) so as not to get a burnt sky or too dark foreground.
Here the filter shows its strengths. The filter can be positioned very easily in the appropriate holder without the risk of slipping. This allows you to get beautiful photos even at long exposures.

For expansion I will add more filters of this brand later.

I can make a clear purchase recommendation!

Hard to beat packaging, presentation and value for money!!!
Absolutely delighted! K&F did a lot of things right here! When I unpacked the adapter rings and the holder, I was already very satisfied. Metal case from 48 to 82 rings. But then the glass, it is packed in a leather case, very high quality! This is otherwise only known from very large brands and companies, which can also be paid well for expensive money, but the price is right here! Only the German translation in the instructions leaves something to be desired! Doesn't flow into my rating! I can overlook that! Dear K&F team, please keep it up! An absolutely overwhelmed customer that you won with me!

Hammer quality for the price
Of course, in preparation for our round trip, we also needed a good filter system. We spent months reading, getting information, watching and comparing videos. In the end we decided on this system. And that was a great decision! There are definitely better systems out there, but also for a lot more money. Everyone has to decide for themselves whether a hobby photographer really needs it. With this system, we are talking about real glass - not plastic! The glass is not colored but coated, so there are no distortions or blurring at the edges. The only drawback is that the glasses are quite difficult to slide into the holder - BUT nothing slips out and nothing slips. Perfect for quick position changes. We got used to it quickly. The results with the filter are as desired, there is nothing to complain about. We are thrilled and would choose this filter system again and again. We bought the kit with the holder including all adapter rings, the graduated filters, the 64 and the 1000 - everything was great! Have fun capturing memories!

Value for money is great, I would buy again
I've been taking photos as a hobby for several decades, first analogue, then of course almost exclusively digital for 15 years, i.e. I've seen and tried out a number of photo accessories over the years. With the filter I bought here, three things were decisive. 1. The quality, I've spent too much money unnecessarily on useless photo accessories 2. The price, I don't see an point in spending more money which you don't see in the photos afterwards anyway 3. The durability and expansion of a plug-in filter system Attached Image with the graduated gray filter All points speak for this product. The filters are quickly attached, make a stable impression and are supplied in a practical case. The plug-in filter system is more than useful for the hobby photographer. In any case, I wouldn't want to be without it in my photo bag. I can't understand the fact that the filters are difficult to insert, which is often criticized here, on the contrary I even find this important because otherwise the filter could quickly fall through. After more than half a year and several sessions, I can only say about the durability of the filters, so far nothing has been scratched or even broken. Conclusion: Anyone who takes pictures knows that this hobby can sometimes cost a lot of money, and often with this hobby it really is so; "If you buy cheap, you buy twice". However, I don't have the impression with this product that the more expensive competitors, who also offer plug-in filter systems, do it so much better that the surcharge would be worth it here. That's why I can only recommend this system
Value for money is great, I would buy again

clean course
the quality of these filters seems to be on par with others (more expensive ones). The course is clean and evenly straight. The very well thought-out pockets, with their pull-out tab, offer fingerprint-free handling. Clear purchase recommendation on my part...!!!

No, it's just the filter with case. But any brand of 100mm square filter holder kit will work (Lee, Kase, Nisi, Tiffen, etc) which accept 2mm thick glass filters. I have Kase one.
