I've been wondering about this - what happens on an OM-2s(p) when you
switch from auto (CWA) to manual (spot) metering? The mechanical
arrangement suggests that the same light is being metered by the same
sensor, so is the auto-preview reading also a spot reading? (it doesn't
appear to be) otherwise, how is the metering area changed?
