The odd thing is ... the results are consistent when using it from a tripod (thus I got the MTFs and they are Ok).
However, when using it handheld with activated AF, some images show a clear deterioration on the lower left.
I'm slightly wondering now.
Is this a centering defect ?
Or does it relate to using this lens on an Olympus camera where the IS is deactivated ... thus maybe not properly "locked" ?
There's no mechanical switch for the IS after all.
