For your criterion of pure optical quality, it has outstanding
resolution, but considerable field curvature and pincussion distortion
<http://homepages.caverock.net.nz/%7Ebj/zuiko/00001.htm>. So it won't
compete with the 90/2.5 for flat subject copy work, but might just
outperform it for natural subjects. Field curvature can actually be an
advantage for some 3D subjects, depending on the direction, the shape of
the subject and whether you want more or less apparent DOF.
