Hate to burst bubbles here - Transformers 3 is being shot on film, 35mm... I know most of the camera dept. and 3 of the LOST guys/girl is on Transformers 3. FILM. Panavision with some 235/435...
If you read the article that the OP posted, it says the guy working on Pirates 4 here in HI, he says they will shoot 3D THROUGHOUT production. Nothing about it being a 3D production. Most likely, the action seq will have some third dimensional crap...
Uhhhhh, dude, I'm afraid you dont have any of your facts in order. This film is most definitely being shot digitally IN 3D with the following three cameras.
Arri Alexa
Panavision Panaflex Cameras, Panavision C- and G-Series Lenses
Sony CineAlta F35, Zeiss Master Prime Lenses
While the Panaflex is a 35mm camera, apparently the majority of the film is being shot with the Arri Alexa w/ pace rig attached
Just google pictures from the set and you will see pictures of these three cameras.
(You can identify the pace rig by the dual camera rig, one horizontal and one vertical with a beam splitter in between.......look at the link posted below).
