Let me reiterate the UNscientific part. There are enough technical comparisons out there. This is a camera user, gut feel impression between the two. I've used the OM-D extensively for a few months. It is a great camera. Great image quality, great handling (with the grip), and enough accessories and lenses to keep most anyone happy. But then Sony released this damn NEX-6. I never quite bought into the Tri-Nav thing. Too many dials too close together for me. But the NEX-6 fixed that. 24mp out of an APS-C seemed like a bit of a push to me, the NEX-6 fixed that. The kit zoom (I love and use kit zooms) was too big on the NEX-7, the NEX-6 fixed that AND (very key to me) went to a 24mm equivalent! A 24-75 will cover 90% of my photo needs. Yes I know the limitations of kits zooms, but I'll take the convenience of having the range. My choice. So here they are. I'll post a few comments about each. If you have real world questions, ask. I'm more one of us, not a reviewer.
