When working with a macro lens on 4/3 the working distance is longer 
than would be the case on full-frame... provided you accept equivalent 
angle of view rather than magnification as your measure.  That is, the 
4/3 angle of view at 1:2 is the same as the full-frame at 1:1.  At 1:2 
the lens to object distance is greater and the lens to image distance is 
less... advantage to 4/3.  But, if you insist on doing 1:1 there is no 
difference.

Sorry, more than 20 words.
