Now for the details: I have the original system of Cokin filters and various adapters and am very satisfied. The holder here is processed significantly worse compared to the original (for example, has several ridges) and the insertion of the filter is something hakelig. Anyway, you can use the holder for occasional use entirely.
The contained in the set lens adapter fit quite well on the microphone stand, however, have to the original of Cokin some play. One can live without that, but if you value on precise alignment of the filter, may be seen a limiting. Conversely sit the original adapter on the filter holder in this set very tight.
Conclusion: for occasional use ok. I bought the set in order to provide some exotic lenses can. Due to the number of adapters to making it so completely equipped.
