NEX-5N, NEX-5R, NEX-6 and NEX-7 has good video quality too, but somehow its autofocus is not that fast. That's why its video quality is not as good as GH2 and GH3. I am not saying NEX doesn't have good video. If count top 5, NEX-7, and NEX-5? should be on the top 5 list.
One strange thing for NEX-5R and NEX-6. Sony added phase detection in addition to the constrast detection for the autofocus. Somehow, it doesn't improve much in terms of auto focus performance. Its autofocus speed is still behind those using constrast detection only cameras, such as GH?, and OM-5.
Somehow Nikon 1 systems(V1/V2 and J1/J2) use both phase detection and constrast detection. Its autofocus is as fast as top of line mirrorless cameras, GH? and OM-5.
