Title: Is this a Tiffen filter?
Review: purchased this one as spare filter for lens, not happy for the problems, anyway, you get what you paid.1st problem, the light would be reduced 20~30% after this filter was attached, and another hoya filter will not reduce any noticeable light; 2nd, the lens cover cannot insert to the filter deep enough, as the original lens or hoya filter.
