For the most part, their product lines (at least, the more popular ones) are non-overlapping. As I stated elsewhere,B+W is excellent for round/threaded filters, but they are not the place to go for rectangular filters. If you want a graduated ND filter, B+W's circular ones are not a good solution (the quality is excellent, but for creative purposes you almost never want the graduation in the middle of the image). B+W also doesn't make anything like the Vari-ND filters offered by Singh-Ray. Singh-Ray does make excellent resin graduated ND filters, and their variable ND filters are also nice.


But, I do think there's definitely a big element of marketing hype in Singh-Ray's products. Here are a some reasons that I feel that's the case:


There's a statement in Singh-Ray's FAQ, "<span>Q6) Are your filters multi-coated? A:No. We have carefully evaluated multi-coating of filters, and in our opinion, the benefits are negligible, and outweighed by several disadvantages." Personally, I'd like to know what those purported disadvantages are in Singh-Ray's opinion, and how they were 'carefully evaluated'. To me, that sure sounds like a marketing statement. It's pretty generally held that multicoated filters result in less reflection and ghosting/flare/glare than single-coated or uncoated filters. In fact, although Singh-Ray states that their filters are not multicoated, they don't state whether they are single-coated or uncoated. I like to know what I'm buying. Maybe it's ok if their filters are uncoated, though - their RayVu cleaning solution, "...applies a crystal-clear coating to resist fogging, dust, and finger prints [and] ...tends to slightly increase light transmission and color saturation."Personally, I like my filters to be (multi)coated and my cleaning solutions not to leave a residue behind. But, that's me.


Another reason is transmission curves, which provide a quantitative way to evaluate filter performance. B+W publishes their data, both separately and at the back of their filter handbook. Hoya's data are at the back of their catalog. Where are Singh-Ray's? Apparently, they don't make them available.
