And if I have understood things correctly, the very telecentricity which is
such a vaunted advantage of Olympus digital lens designs actually
contributes significantly to reduction of the size of the out-of-focus areas
of an image. Your samples seem to support that - perhaps the more so when
we see the next results from the 50mm primes.

I've yapped unendingly about aspherical elements and also about the
restricting of the size of the out-of-focus blobs with modern lenses. This
comparitive illustrates it perfectly. I truly believe that this restrictive
blob-expansion is what makes so many modern digital images look so flat AND
why FourThirds has been such a whipping boy for inability to isolate subject
from background. DoF calculators assume symmetrical lens designs and
non-aspherical elements.
