I have some cheap Coleman polaroid sun glasses. When at the angle to cut out reflections, the ones it does pass are blue. As sunglasses and I seem to break up often, I never spend much money on them...and i don't mind the blue reflection artifact.
I have some in expensive Vvitar and Tiffen camera polarizing filters. They show this blue reflection ever so slightly.
I have bought B+H and Hoya filters for my DSLR gear (usually UV "lens cap" filters for the hardened glass)...and at 5x the price of Vivitar and Tiiffen filters.
I have to wonder if there is some unobtanium special construction/material that would make a diff for the polarizing filters. Comments? Please, no strafing runs about the use of polarizing filters themselves. De gustibus non est disputandum and all that.
