I bought the graduated filter because it was recommended to me by acquaintances.

I wanted a filter holder with these characteristics and an ND filter to start my first steps in long exposure. I chose this brand because I usually like what it offers (and, especially, pretty much adapted for the price it offers) A sturdy metal filter holder with a safety trigger to place on the adapters and an ND 1000 filter that works perfectly is to start with this type of photo even in the light, see the photos, it comes with a leatherette cover with a soft velvety inside so that the glass and the filter holder are not damaged, even though it is presented in the box without a cover.

I have long played with the idea of buying a graduated filter, but the prices of Nisi, Haida, etc. around 150 euros have always deterred me. Then I came across the filters of K&F, since the filter was in a Preislich favorable frame I ordered them.

For a while I had been hesitating between several brands to choose a filter holder for ND and GND filters. I took advantage of a flash sale to buy this kit. I am not disappointed.
The set seems sturdy and easy to store.
The case, quite pretty, has 5 compartments, 3 of which, for square ND filters, are raised via a ribbon. On the back of the case, there is a belt loop and a belt loop. I would have liked a slightly more spacious compartment to house the adapter rings with the CPL filter when it is removed.
The assembly (or disassembly) of the elements is well explained in instructions in several languages, including French.

Main positive points:
No dominant color, nor loss of sharpness on the first tests carried out.
The plastic frame with its tabs to handle ND filters.
The system for installing the PLC filter on the filter holder.
the knurled button for mounting the adapter ring and for rotating blocking the filter holder.
The very accessible wheel to control the polarizing filter.
The sturdy holding of the square filter on the filter holder.
The robustness of the metal filter holder.

If you have to find slightly negative points: Keeping
the square filter a little too sturdy in the filter holder.
The click too loud to lock the CPL filter in the filter holder.
No pouch to independently protect the CPL filter in the case.
No protective cover for the CPL when the set is installed on the lens.

I use it for long exposure photography.

I've used the filter several times and it works great plus the mount works great and have already used other filters with it...

Apart from the fact that it is an excellent product, the customer support is absolutely great, I have rarely been treated so reliably and friendly, big praise.

Since I haven't worked with ND filters before, I don't know what I could complain about here.
Overall I am very satisfied with the glasses from K&F. You get a high-quality, processed filter with top optical quality and a good scope of delivery (artificial leather case).

Ich war länger auf der Suche nach einem Rechteckfilterhalter und wurde nach längerer Recherche bei diesem Anbieter fündig.Der Halter wird mit 7 Adapterringen mitgeliefert und lässt sich somit an verschiedenen Objektivdurchmessern befestigen.Der Adapterring wird auf das Objektivgewinde gedreht und der Halter einfach auf den Ring montiert.Die Halterung hält sicher und gibt mir keine Bedenken, dass sie nicht halten könnte, auch wenn sie minimales Spiel hat.

Good quality of the filter.
