I always thought that the early OM-2 models were centerweighted when
measuring off the curtain, and full frame averaging when metering off the
film. So as shutter speeds got longer the amount of center weighting
gradually diminished. With the change to the new curtain pattern I thought
the center weighting was somehow built in to the way the photo cells read teh
light, so there is the same amount of center weighting at all shutter speeds.
Then again, I could be wrong...
