Lou,
Is there a specific method you know of to test for the focusing 
problem above?  If it is determined that this is an issue is the 
only method to fix, a trip to the factory?  I have a 10D that I have 
always thought had this issues but I have assumed that I would 
sometimes use to shallow a DOF.

Thanks,
