I have a Hoya 77mm polarizer that is mint. However, it's a linear polarizer, and I have found out since buying it that supposedly it doesn't work with digital cameras. It's a nice polarizer, and it would take a good hundred bucks to replace with a circular polarizer. Basically... I'm wondering why exactly this won't work? I've taken some test images and honestly I can't tell what people would mean by the polarizer not functioning correctly with a digital camera. Anyone have any info on this?
