It appears you can use the shutter button for auto focus, just as you do in still photography, by holding it down halfway, letting the camera focus, then releasing. Very handy for a quick focus shift.

We have to wait and see how well it works, the manual recommend not to use it because aperture might change during recording, I don't think they improved any over the 5D focus for video but I hope that I'm wrong cuz I don't mind pressing the shutter for instant focus with any focus point I choose.

And it has the ability to take stills simultaneously... hmmm, this camera is really starting to sound interesting...

The video is stopped for a couple of seconds when you take a picture! I wonder if it starts a new file or you can have a video clip with a "hole" due to the picture...

The data rate is ~12+ mins into 4 GB for a data rate of ~40 Mbps. The limitation isn't the flash card capacity. The limitation is the maximum file size that either the FAT16 or FAT32 filesystem will support. So you can have a very large capacity flash card with multiple 4 GB clips on it.

I wonder if it starts a new file or you can have a video clip with a "hole" due to the picture...It works exactly the same as the 5D Mk. II. It does not start a new file; it simply records a freeze-frame for 1 sec.
