was using this filter in a cloudy day for taking pictures at the flowers to see if the rendering colirs are affected

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!

These filters are an absolute highlight, convincingly good quality, everything fits perfectly, everything is high-quality and securely packaged and safely protected for transport in beautiful cases. The first tests are promising, but I currently don't have a suitable motif to test the full strength of the filters, but I'm absolutely confident that excellent and convincing pictures can be taken with them.

A mild light reducer. Can be easily plugged in together with other medium-strength ND filters. Quality like other manufacturers offer. Good optical glass.

I am a passionate landscape photographer as a hobby and have now switched from the screw filters to this rectangular filter system from K&F. The screw filters were all fine, but you don't have the option of attaching a graduated filter to the ND filter in order to achieve even nicer effects. It is mounted on the lens using so-called adapter rings, which are included in the most common sizes for lenses. After attaching the adapter ring to the lens, the filter holder is attached. This is secured by a small lever (spring-loaded) and later released again with this. Now you can slide the filter plates into the filter holder. This lifts a bit severely but it should also hold and must not wobble. It is also important to observe that the filter used is close to the lens so that no more light can penetrate between the filter and the lens, which could possibly ruin the recordings. In terms of quality, the system makes a good impression considering the price. The only thing I noticed negatively is that the filter holder has some play after it is placed on the adapter ring and why there is no adapter ring for a 55mm filter diameter in the set, I also ask. 55mm is a common diameter for lenses. I can highly recommend the K&F system for amateur photographers. The professionals will probably use filter holder systems from other manufacturers, but they also cost a lot more.

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!

I like that it filters out the light pollution and still provides natural colors of the objects in the night sky.

Great light pollution filter. this filter cuts the light pollution out which enables me to get the long exposures I need to image deep sky objects.

I was debating between the K&F Concept ND filter and some other brands. BUT, I am really happy that I went with these because the build quality, picture quality, and performance are out of this world! Great ND Filter for videographers with hard spots.

These filter help reduce urban streetlight pollution by filtering out the yellow light. Must have for Astrophotography.
