Modern Photography Zuiko Lens Tests

I have included the correlation tables between the numeric ratings and
the qualitative ratings at the end.  Note, however, that MP doesn't seem
to follow these tables very closely themselves!  Thus, the best method
to use when comparing two lenses of the same focal length is to compare
their numeric ratings only, ignoring the qualitative rating.  As far as
I know, lenses without a reference were never reviewed by Modern
Photography.  Lenses with a reference but no data will be added as I get
the articles.

I. Fixed Lenses for OM System
