Noisy cameras were an issue when the industry transitioned to talking pictures. Cameras were put into soundproof enclosures that made them even more huge, and like rolling a small truck around on the set.

You'd think there would be a lightweight soundproof solution for the IMAX cameras.

It sure would be the spirit of Star Wars if Ep VII will pioneer somethong useful and particular for the future of filmmaking, just as the OT pioneered certain technology. For all we know, that picture BadRobot posted could be showing off that answer - the future of IMAX cameras.

If that isn't enough, what if VII will then be the first full-length feature film to be shot entirely using IMAX cameras. There is that chance and that would be groundbreakingly awesome :)
