Thanks, just done a quick google of those the cameras above and I think the 5Dii the most likely candidate. I'm now working my thru the manual.Canon's ONLY FF cameras are
5D, 5Dii
1Ds (whether it is Mkiii or Mk ii)
You HAVE to remember the "s" in the 1D, it stands for Studio. 1D are 1.3x cropped. Every other cameras are 1.6X cropped, including the 7D.
Basically, Canon's best 1.6x cropped body is the 7D.
The latest FF camera is the 5Dii (the 1Ds Mkiii was release before that).

Yep, it's shot frame by frame, so I'm not really sure why they don't use D700's as then there would no need to adapt the Nikon lenses then. I'm guessing that the extra resolution of the 5D may be needed, especially if the final film is going to be aired in the cinema on a big screen.I know of a couple of people using DSLRs to record stop motion animation - something about needing the Nikon 'non-G' lenses with their aperture control to help control/avoid flicker?
What I don't understand is why they all seem to want to shoot on a Canon. Correct me if I'm wrong, but I thought SMA was shot frame-by-frame? So why not shoot it on a Nikon body?
I'd imagine manual focus will be used so video mode or superior AF won't really be factors here. Maybe there is some custom software used to control the cameras that works better with Canon bodies?I can't think there's much relevant difference... the 5DII does video, the D700 has far superior AF and shoots faster - that's the highlights but they don't seem relevant here. I'm guessing it's probably just done that way out of habit rather than a requirement to use Canon cameras.
