<<Yes and no. The circular polarizer is needed when a beamsplitter is
present in the mirror assembly of a camera, since this beamsplitter
itself is a kind of polarizer, so it won't properly see the light
output from a normal linear polarizer.>>
Thanks Dave. This is the easy answer I was looking for. :-)
I believe spot meters were common long before circular polarizers were,
or beam splitters for that matter.
