It will never replace my DSLRs but as a light-weight, walk-around rig it has great potential. I'll be ordering the next model as soon as it's announced.
While shooting video the auto-focus of my Sony NEX-5n will keep a person in focus as they walk around a room, no problem
The Panasonic GH3 has better video specs than a 5D3 -- 60p (NTSC) / 50p (PAL) progressive recording
72Mbps (ALL-Intra) in MOV format ,for only $300.00 more that the rumored price of an EOS M2. Canon needs to wake up and see what the competition is delivering.
You missed my point a bit. I don't want autofocus for video. For the kinds of things I do, autofocus can often be more of a hindrance than a help. I'm glad your Sony can AF for you and if the M will AF with the kit lens in video mode, well, that's good. But I'll keep it shut off. Just works better for me that way.
And as far as the GH3 vs 5D III - unless you've shot with both of them and can back up your statement, your opinion is irrelevant. I'm a photographer for a daily newspaper and I own a 5D III. I shoot stills and video with it on a daily basis. If the GH3 truly is better, it must be a miraculous machine.
