Philip gives his conclusions on these cameras in the second part of his comparison. It's a 32 minute video!
I'll focus on his thoughts on the Sony NEX-FS100 as it's the new camera in the bunch. Ultimately, his observations aren't completely unexpected. His biggest complaints are about the lack of ND filters and HD-SDI output, two features that the other two cameras, the Sony PMW-F3 and Panasonic AG-AF100, offer.
He likes the picture quality of the EVF, BUT it's limited in how it can be used due to limitations in the movement of the LCD, so he still thinks you need something like the Zacuto EVF for monitoring.
The single SD slot and lack of an internal microphone are minor annoyances, and he's annoyed that there's no international version that does 30p, 24p and 25p recording. BUT "this is a really nice camera...the image out of it was so lovely...and in low light the image out of it is absolutely fantastic."
So, the AG-AF100 or the NEX-FS100? For him it comes back to the lack of ND filters and HD-SDI output, two features the AG-AF100 have, BUT, the NEX-FS100 has a nicer picture...
