What brands of cameras were used to shoot the films Avatar, Transformers and Iron Man?

I don't know, but it's an expensive camera, especially the whole movie Avatar is shot with IMAX camera (which can be said to be the highest level of human imaging technology today), far more expensive than TV stations or TV series. It is estimated that a camera can invest in several China movies.
