OM-2s mirror is only 'partially silvered' in the area related to the
meter... same with the OM-4 and OM-3 I think. Therefore there is a slight
difference in the brightness of the middle area of the screen, which I think
otherwise would be the brightest and is toned down to be more evenly matched
to the edges and corners. I've never noticed any uneven illumination in any
of the OM-2s, OM-4, or OM-3 bodies I've looked into.
