On the first Dune, as explained in Dune Was Shot on Alexa LF Then Transferred to 35mm Film Then Scanned Back to Digital, the production used a digital acquisition pipeline with a film intermediate. Moving to native 65mm and IMAX 70mm acquisition changes the lens requirements substantially because the format is less forgiving of edge falloff, coverage limitations, and inconsistent rendering across the image circle. Directed by Denis Villeneuve and shot by cinematographer Linus Sandgren, the film continues the franchise’s large format approach while introducing a new optical pipeline tailored specifically for IMAX film capture.
