I recently went to the local photo supply store looking for a Hoya circular polarizer. To make a long story short, I came away with a generic brand (Werner-Hollingsworth) 72mm. They did not have any Hoya, Tiffens, or any of the other well known brands in stock, and I needed it for this weekend.
My question is - are there differences in tonality, or differences in total overall polarizing correction between brands? Or do they all pretty much work at the same level? I'm not refering to multi-coatings, or any other physical differences.
The reason I ask is that the filter doesn't seem too bad at all in its construction and operation, but I begin to wonder if there are other things that would differentiate a generic filter from a name brand, other than construction quality. And I don't have any others to compare from.
Any insight would be greatly appreciated, as I will return this thing next week if it turns out that there are in fact differences in overall effects.
