I think the micro 4/3's camera refers to cameras with a certain size sensor. A Nex is not a micro 4/3's camera bec it has a APS-C size sensor. Is that correct ? thanks joanlvh
Yep. The m4/3's have a 2x crop factor, whereas the NEX's have a 1.6x crop factor. NEX's have the bigger sensor, but m4/3 has the bigger lens selection (not counting the NEX adapter for Sony SLR lenses).
