Absolutely no room for error with focus on HD. There are some very
effective focus assistance tools (peaking etc) on proper video rigs but
a shaded and contrasty viewfinder is essential on any camera in bright
ambient light.
The guy giving the lecture I attended said they used a Canon 7D modified
to take PL mount lenses and an external video monitor where focus was
really critical.
I also found out from another source that Zeiss now offers their CP.2
Cine lenses in Canon EF mount so you wouldn't have to modify the camera.
What I understood from the lecture is the real advantage to the DSLR
video was using the 5D with its "full frame" 135-format sensor to get a
film like quality to the captured video in a rig that was so portable
they could do things they never could do before with the real big rigs;
mainly because they could now get into places they never could fit the
big rig.
I don't think DSLR video is going away, I think the pros are going to
get a dedicated box that has the 5D sensor but won't have the un-needed
pentaprism housing, and will have the capability of simultaneously
outputting to the LCD on the back and to external video
monitors/recorders/whatever.
That was what he said was the main drawback. They couldn't use live view
at the same time they were using external monitors.
