I did not specify a camera but was doing the devil's advocate thing.  If as you
say (and who am I to disagree)that a two cross angled polarizers either linear
or circular will operate the same for a T-10, the mystery remains about why
Olympus would go to the expense of circular filter.  I even went back to my
unscientific hand held testing and used a circular with a linear, and it
eliminated the metallic glare as well.

As to cameras, I have an OM1, OM2, OM2n, OM4 & OM4T. - I'm in way to deep.
