Todo en es perfecto

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

The adapter rings allow us to place the filter holder on any lens, as we have a large number of different diameters. They are made of black metal and well finished. With labeling on each ring with the corresponding diameter.The filter holder is metallic with the part where the filters go from a kind of hard plastic. Two 100x100 filters fit and 100x150mm gradients without any problems. The attachment system to the adapter ring is via a very manageable metal tab.In several tests I did under different lighting conditions, I did not notice the entry of residual light through the space between the filter and the filter holder. The photos have a slight magenta tint that is very easy to correct when editing, but it is not at all overdone. I am very pleased and enjoy it very much. I recommend it!

Ich habe schon lange mit dem Gedanken gespielt mir einen Verlaufsfilter zu kaufen, wobei mich die Preise von Nisi, Haida usw. um die 150 Euro immer abgeschreckt haben.Dann bin ich auf die Filter von K&F gestoßen, da die Filter in einem Preislich günstigen rahmen war habe ich sie mir bestellt.

The filter does what it is supposed to do, it extends the exposure time. I haven't noticed any vignetting or wrong color reproduction so far. And so I'm satisfied. The packaging of the filters is very good and practical, which some higher-priced filters can't do that well.

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.
