Ah, yes, that is correct. I must confess, there are so many things 
that appear to be metal that do polarize light, I forgot that reflex 
mirrors aren't on eof them. My F-1 does polarize the light at the 
focussing screen only.
.......
   The F-1 focusing screen has a beam splitter, which redirects (but doesn't
polarize) some of the light towards the meter.  When a linear polarizing
filter is used on the camera, is causes metering problems. A circular
polarizer illimimates this problem.
