==== Film cameras ====

The IMAX cinema process increases the [[image resolution]] by using a larger film frame; in relative terms, a frame of IMAX format film has three times the theoretical horizontal resolution of a frame of [[35 mm movie film|35 mm film]].<ref name="Slash Film">{{cite web|url=https://www.slashfilm.com/film-interview-imax-executives-talk-the-hunger-games-catching-fire-and-imax-misconceptions/|title=/Film Interview: IMAX Executives Talk 'The Hunger Games: Catching Fire' and IMAX Misconceptions |publisher=Slash Film|date=December 2, 2013 |access-date=December 17, 2013}}</ref> To achieve such increased image resolution, which IMAX estimates at approximately 12,000 lines (6,000 line pair modulations) of horizontal resolution (18K),<ref name=imaxresolution /> [[65 mm film]] stock passes horizontally through the IMAX movie camera, 15 perforations at a time. At 24 frames per second, this means that the film moves through the camera at {{convert|102.7|m|sp=us}} per minute (just over 6&nbsp;km/h). In a conventional 65&nbsp;mm camera, the film passes vertically through the camera, five perforations at a time, or {{convert|34|m|sp=us}} per minute. In comparison, in a conventional 35&nbsp;mm camera, 35&nbsp;mm film passes vertically through the camera, at four (smaller) perforations at a time, which translates to {{convert|27.4|m|sp=us}} per minute.<ref name="Slash Film"/>

In the [[Todd-AO]] 70&nbsp;mm-format of widescreen cinema, the image area of a 65&nbsp;mm film-frame is {{convert|48.5|x|22.1|mm|in|abbr=on|sp=us}}; in the IMAX-format of widescreen cinema, the film-frame dimensions are {{convert|69.6|x|48.5|mm|in|abbr=on|sp=us}}. To match the standard image resolution of the moving image produced with the film-speed of 24 [[Frame rate|frames per second]], an IMAX film requires three times the length of (negative) film stock required for a 65&nbsp;mm film of comparable scope and [[Cinematography|cinematic technique]].

In March 2022, IMAX announced a new initiative in cooperation with [[Kodak]], [[Panavision]], and [[FotoKem]] to develop "a new fleet of next generation IMAX film cameras", with a goal to deploy the first four units in the next two years. [[Christopher Nolan]] and [[Jordan Peele]] are among a group of advisors, made up of filmmakers and cinematographers, assisting in identifying new specs and features for the prototype development phase.<ref name="IMAX Corporation">{{Cite web|url=https://www.imax.com/content/imax-to-develop-new-fleet-next-generation-imax-film-cameras|title=IMAX® to Develop new Fleet of Next Generation IMAX Film Cameras|date=March 22, 2022|website=www.imax.com}}</ref>

In a May 2024 interview with [[Collider (website)|Collider]], IMAX CEO [[Richard Gelfond]] revealed that there will be four new identical cameras that will be 30% quieter than the existing cameras.<ref>{{Cite web |last1=Weintraub |first1=Steven |last2=Jones |first2=Tamera |date=2024-05-20 |title=IMAX Reveals Their Ambitious 6-Year Plan to Expand Across the Globe |url=https://collider.com/imax-global-expansion-plans/ |access-date=2024-06-04 |website=Collider |language=en}}</ref> ''[[The Wall Street Journal]]'' revealed that the new cameras will be made out of carbon fiber and titanium, and they will feature a five inch color display along with wireless capability.<ref>{{Cite AV media |url=https://www.youtube.com/watch?v=6DAFkaGUiT4 |title=What Makes IMAX So Expensive? {{!}} WSJ Tech Behind |date=2024-02-29 |last=The Wall Street Journal |access-date=2024-06-04 |via=YouTube}}</ref>
