I'm looking forward to the on-going coverage of this camera. When I saw it at NAB, my initial impression was, "Aside from tripod use on an interior set, this thing is basically unusable." The rear screen is not gonna work in sunlight. Image quality aside, if you can't see the image in the viewfinder, to the Operator it's useless.
And, as Michael says, absent some kind of complex rig, hand-held work is out.
Silly, really. Raw or not.
