C.H., just to remind you that a true macro lens performance is optimized
to be best at _close_ distances, whereas the 100/2 and 55/1.2 are likely
optimized for best performance at infinity.
IMHO, with the 50/2 and 90/2 macros Olympus did an admirable job of
balancing these contradictory requirements, but I bet that your above
results are "by design" rather than an accident.
