K&F Concept 100X150mm Graduated Neutral Density (GND) Filter HD Optical Glass Waterproof ND Lens Filter Kit

The package is divided into 3 parts:
1. A bag with the adapter metal rings for different diameter lenses.
2. A box with the filter and its transport leather case.
3. A box with the filter holder.

The adapter rings will allow us to place the filter holder on any lens since we have a large number of different diameters. They are black metal and well finished. With inscription on each ring of the corresponding diameter.

The filter is made of glass made in Germany. It is a square ND1000 filter 100x100 mm and 2mm thick. It allows us to remove 10 stops of light to take long exposure photos with daylight perfectly. In the example photo that I have posted, it is taken at 30" at noon. I love the play that can be achieved with this filter.
The filter comes in a leather case with tissue paper lining the inside. The case is rigid enough to protect it properly.
The glass is not easily marked by fingers and does not attract dust.

The filter holder is metallic with the part where the filters go made of a kind of very hard plastic material. Two 100x100 filters and also the 100x150mm gradients fit without problems. The fastening system to the adapter ring is by means of a very manageable metal tab.

In several tests that I have carried out in different light conditions, I have not noticed the entry of residual lights due to the space that remains between the filter and the filter holder. The photographs have a slight magenta tint that is very easy to correct in editing, but it is not exaggerated at all.

With the complete kit and the price it has, it is a fantastic filter to experiment with and achieve excellent results. I'm really delighted and I'm enjoying it a lot. I recommend it to you!
