Jon,
The OM-1, -2, -2n are unaffected by the polarizer i.e. you can
use either linear or circular polarizer with no difference. The OM-3 and
OM-4 (and I think the OM-2sp) utilize a half-silvered mirror for the
metering results you see in the viewfinder. A linear polarizer will
throw off this indicated metering and if you want the reading to be
accurate you must use a circular polarizer. However, since all of these
bodies use "Off-the-film" metering (with the mirror flipped up) the
polarizer has no effect on the exposure going to the film; there will
simply be a difference in the metered exposure (inaccurate) vs the film
exposure (accurate). Hope that's clear as mud. ;^)

Subject: [OM] OM-1 Polariser/Polarizer
Hi Everyone,
A very quick, On Topic question for you. I can't remember the exact
details of which, when, and why, but I remember something about not
being able to use a Linear Polariser on some OM cameras (OM-3 & 4 ?) due
to the spot metering ? My father has an OM-1(MD) and was told that he
needed a circular polariser because "a linear polariser will throw off
the meter in ALL SLR's". Sounds like BS to me. Anyone care to comment
on which (OM) cameras need a specific Polariser, which are not fussy,
and why ?
Thanks, and just to drift it slightly Off-Topic, what about the E330 ?
Or does everyone just add that effect later in PS or whatever ?
Jon
