Just for fun I got out ALL my polarizers today, and looked thru 'm. Sorry I do not yet ascend to the level of B+W filter quality...they are mostly decent older Tiffen USA and well made older Hoya (Japanese made)... and a bunch of no-name Japanese and Korean ones at the bottom of my bag. Maybe five in all, are all linear, I don't believe they are coated, certainly not multicoated. However, I did notice that there was a noticible difference as regards the quality of the image in the finder, which I would assume would be borne out on film. I had never thought to compare them, thought I would throw this out there for discussion. The best one (Tiffen, it turned out) yielded a pleasant image, when dialed down all the way for maximum reduction of glare on a shiny plant leaf... I know it is subjective but it just seemed nice. Also I did not have to darken the image that much to achieve a great deal of glare reduction. Whereas the others seemed to require such polarization that the image was not only darker, perhaps a third stop? hard to say... but the images were just harsh, very dark, as if the zones of contrast were terribly compressed. Not at all appealing.
