I recently purchased both of these cameras with kit lenses. The Oly should outperform the Nikon easily due to specs and age alone. I was so excited about the e-pm2 and only picked up the j1 because it was cheap. I have found the j1 destroys the Oly when it comes to fast , accurate focusing. Snapping a quick picture with the j1 yields a perfect picture nearly every time. I have found the oly needs a steady hand and a double check of its subject. Is it the kit lens quality? Is it the AI? Am I missing something? Should I not be comparing these models? I'm not promoting Nikon as this is the first one I have ever owned. Feel free to enlighten me.
