Mark,
>From the Olympus FAQ file:
Due to the semi-silvered mirrors in the OM-{2S, 3(Ti), 4(Ti),
and PC} you must use a circular polarizer with them, otherwise
your exposures will be off by 2-3 stops. The OM-{1(N), 2(N),
10, G, and F) do not have a semi-silvered mirror, and can thus
use linear polarizers without any problem. This problem
reportedly only affects the spot metering modes of the OM-{2S,
3(Ti), 4(Ti), PC and probably OM-2000}. OTF (normal auto)
exposures don't technically need the circular polarizer, but
why go to all the trouble of carrying two different polarizers
and risk using the wrong one?
I assume that a 4 would also need a circular polarizer.
