Q: about polarizing filters.

[sdean7855]

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.

Polarizers are one area where you get what you pay for. The cheaper varieties will have color casts. It's worth spending the extra money on a higher end filter. I use Singh-Ray.

If you plan to only use them for LF, you can save some money and buy linear polarizers. If you will also use with a DSLR, you will want to stick with the more expensive circular polarizers.

Have a look at this. You have to look at each filter for colour results and these are circular only.
