The OMPC requires a circular polarizer for accurate exposure display. I
think regular Auto and Program modes will give correct actual exposure
OTF. I'm not sure just how ESP metering works, but if it sets the
exposure based on the reading through the mirror, it could give
inaccurate exposures with a linear polarizer.
The manual is not clear on this point. It says "As soon as you fire the
shutter, the camera will measure the light intensity in both the center
of the frame and the outer area separately. The micro computer
then......" Does this mean before or after the mirror goes up? The
manual does refer to the 2 modes as "ESP metering" and "TTL Direct 'OTF'
Light Measuring", implying that ESP is not OTF. Maybe the writer didn't
know either, and hedged his/her bets. In any case, ESP and OTF are never
used together in the manual.

How about the OM-PC - it appears to have a 2-piece mirror.
OM-Gs do not have spot metering or semi-silvered mirrors, so
linear polarizers should work just fine in auto mode, or any
mode for that matter.
