Thank you, gentlemen! Just keep the input coming!

Tom, I do a lot of photography and I presume that a digital video camera is quite "similar"
to a photo camera in the way light is measured. Due to my lack of language knowledgde
Iīve borrowed a few lines from Mr. Michael Reichmann of The Luminous Landscape to explain the reason why I seek a circular polarizer:

"Linear polarizers are more effective and less expensive than circular ones. But circular polarizers are needed with just about any camera that has a through-the-lens metering system, or autofocus.
The reason for this is that both of these systems use semi-silvered mirrors to siphon off some of the light coming though the lens. If that light is linearly polarized it renders either the metering or the autofocus ineffective. This means that you're going to have to buy circular polarizers unless you're shooting with a pre-1970's camera, or a view camera."

Please correct me if this information isnīt valid when it comes to digital video.
