Hi Moose,
I understood that some OM screens do have an effect on OM metering and I
thought I remembered that a couple Olympus screens even come with a warning.
I can't remember which ones, but I don't really believe that is the problem
- these screens aren't that different. The OM4 is a split image focus and
the other is a solid matte.
Anyway, the two cameras are an Olympus OM2n and an OM4Ti. I metered on a
grey card, purposely set out of focus and I used the same lens on both
cameras - the OM4Ti consistently reads 1 EV lower than the OM2n. As I
indicated, I did run a roll of Provia through the OM4 a couple weeks ago and
the results seemed OK and I just submitted a roll taken on the OM2n. I'll
have that roll back on Wednesday.

The screen has no effect whatsoever on meter readings on the OM-2, 3 and
4 series bodies.
From a simple logic point of view, either camera could be off or they
could both be off in opposite directions. The only definitive answer can
come from bracketed test slides or a meter tester used by repair people.
Also, the 4Ti reads in 1/3 stop increments and you haven't said what the
exact reading was or what the other camera is and what its finer than 1
stop increment reading may have been. Just picking the closest marked
speed without regard for the 2 LCD segments between each of the marked
readings doesn't tell very much.
