If I were to choose a zoom, I think the newly announced 14-50 from Olympus sounds pretty good. Nice focal range and made for the EM-5! I don't have any experience with Olympus new lenses, but the quality of the old ones used to be outstanding, so I'd risk that. And it really looks like Olympus is equipping this camera for expert/pro use. The system has most of what you will find at Nikanon.
