Does this filter have a coating? What is the advantage/disadvantage of a coating compared to a filter like the B&W ND MRC
Asked by: Wilfredo
This filter is not coated, Tiffen does make a series of multi-coated ND filters called Digital HT which can be found at the link below. Coating provide the filter with scratch resistance, makes it easier to clean and helps to prevent reflections. https://www.bhphotovideo.com/c/search?Ntt=Tiffen%2082%20ht&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=
