I've got B+W MRC filters on all of my lenses from the second I bought them and never regretted them.

When my girlfriend bought the 85mm 1.8 last year the salesman recommend the Tiffen Digital HT filters over the B+W MRC. According to him they were better and cheaper. At that time the Tiffen was not in stock so we ended up with a B+W anyway, but can anybody shine a light on the Tiffen Digital HT filters?
