Have I bought the set for the adapter rings and the filter holder in order to use so my Cokin filters can. Unfortunately, the filter holder is closely sized to the polarizing filter does not fit only pure. The filter plates can be inserted before, but you can clearly see how the bracket is bent by the consequence that he in turn bad fit on the adapter ring.
No buy rating on the filter holder!
2 stars, because the adapter rings are made of metal and are individually priced at Cokin.
