Cotty, Peter has it right. The circular polarizer is functionally no different from the linear polarizer to your eye, but the linear may not be so satisfactory with your camera's sensors. The reflections (or whatever) may be polarized away, but the autofocus or exposure metering or whatever may be all screwed up. Regards, Bob S.(reformed Physics major)
