Since the DOF on a 4/3 camera at 50/1.4 focused at 3 meters is 80mm both 
ahead and behind the subject, if it were a Canon, they would tell you to 
go pound salt.  It's well within the spec.  :-)

Actually, I think the spec refers to depth of focus (which isn't quite 
the same thing) but close enough.  You might choose to read this (or 
not) <http://dougkerr.net/pumpkin/articles/AF_accuracy.pdf>
