I wanted to try long exposures. Since I came in handy the part. The neutral density filter does a great job. The sun is not directly on it seem, but in the shade, he does exactly what he should. The filter is made of a not very hard plastic, which may possibly have scratches result. In the replica holders for Cokinfilter he fits in well. To try out this gray filter is very suitable. I can recommend the disc to anyone who does not know whether he often needs him.
