Yes, correct and good to point out.  Magnification is a  function of the 
projection and not sensor size but I thought Chuck made the question at hand 
clear.  The terminology could use an update.

What many care about more is what the image looks like.  So an image at 1:1 
with a 120mm lens on full frame would require use of a 60mm lens on 4/3 at 1:2 
to appear about the same.  The working distance
is about the same as 90mm lens on full frame.  That is the point. A longer FL 
macro lens would be welcome. 

Don't spook the critters, Mike
