Well, be careful there.  Don't forget to refer to the "diffraction 
limited" lens resolution limits at the bottom of this page from 
Luminous-Landscape.
<http://www.luminous-landscape.com/tutorials/resolution.shtml>

It says that a 4/3 sensor can't resolve more than 8 MP at f/8 or 17 MP 
at f/5.6.  Of course, those are purely theoretical numbers for 
theoretically perfect lenses which don't exist.  In any case you'll have 
to stay wider than f/8 if you hope to get the full 10 MP resolution of 
the E3 sensor.  Unfortunately, some OM Zuikos don't hit their stride 
until f/8 or f/11.  OK for a modest size full frame sensor like the 5D 
but not OK for those even more pixel follow-ons.  The E-1 is probably OK 
down to about f/10.
