I am sure your right Dave, but I am sure it had something to do with the way the light transmission occured, as I said, it was not formal testing in any way shape or form, I have a really good article around here about polarisers I will have to dig out, that explains a great many things...I think that it really depends on the cameras itself, I know I have been told many things, then found out in my particular case the information was not as I was told, like many things in photography.
