Careful there, the spot mode on the 2SP only works in manual mode, while
Automatic and Program modes are averaging. It's an either/or camera,
manual/spot or auto/average, but no mix and match. Since you say your
problem is in auto mode, the 2SP won't help. The OM-4 has both with both.
The earliest production of the OM-2 had a sort of center weighting
favoring a central horizontal band. See
<http://brashear.phys.appstate.edu/lhawkins/photo/om2-curtains.shtml>
The pattern on OM-4 looks like the later OM-2 pattern. The OM-10 and
G(20) have a very different pattern which is shiny on the sides and
black in a vertical center band. Either they are edge weighted or, most
likely, there is a reversal in the metering system and they are pretty
strongly center weighted. The closest thing to what you are asking for
in the OM world is the ESP metering mode in the OM-PC(40). This is an
early form of matrix metering designed specifically to address the kind
of problem you raise. Take a look at the manual .pdf from eSIF for photo
examples. Put it in Program and ESP and all you have to do is focus.
Of course, you could train yourself to think about lighting, since it is
the core of photography, and give that spot meter button a push when it
needs it. It really is a wonderful metering system.

I am a doofus. Here I have the most sophisticated multi-spot camera,
and I still get fooled by careless use of automatic mode (no spot) in
backlight situations, especially when I am in a hurry. As I understand
it, the OM-2SP has a "continuous" spot mode, which I take it to mean
that it's taking the metering on the center spot constantly.
Barring that, are the (centerweight) metering patterns similar across
all the single digit OMs? Any of them have a narrower pattern than the
OM-4/T?
