  1. How long does it take to change 1000 foot film reels in the Photosonics 4b or 4c? (If you can answer for both, that would be great.)
  2. Thank you so much! This really satisfied my curiosity!
  3. I want to see if I could match or surpass Kodak IMAX film in the blue layer of the film using the sharpest medium format or Panavision Shero 65 lens used at its sharpest aperture with a full-frame 8k digital sensor using full-frame lenses with vista vision sized image circles (no higher than MTF 40 on either film/sensor + lens system). I'm not trying to shoot a movie or anything, I'm just curious.
  4. What specific Hasselblad lenses are they? What were the ones they used for Dunkirk? I know that you could look up the focal lengths and apertures on websites such as the ASC website, but they didn't mention the specific lenses that they used. Same thing with the Mamiya lenses used for the Dark Knight Rises. Also, there are no specs that I am aware of for the Panavision Sphero 65 lenses. Maybe I'll just look up the sharpest 6x7 Hasselblads and Mamiyas at the focal lengths mentioned in the ASC and British Cinematographer websites, but I am not sure where to find info on the Panavision Sphero lenses on lp/mm resolution or MTF.
  5. What is the lp/mm resolution of IMAX lenses at MTF-50? MTF-60 would be better in my opinion (if you have that info, but you don't have to give it out).
  6. What is the resolution of a rotary prism camera like the Photosonics 4b or 4c vs a Pin Registered camera like the Photosonics 4er? (If you can include mtf contrast loss data, then it would be good).
